Abstract

The present invention discloses a method for automatically synchronizing the real time of an OS and its related components, and relates to the field of time synchronization. A corresponding time zone mark is generated according to the time zone of the RTC time, the RTC time is used as the system time of the OS, and it is judged whether the time zone represented by the time zone mark is consistent with the time zone represented by the time zone definition of the OS. If they are consistent, the system time is converted into the real time according to the original time conversion configuration of the OS, and if they are inconsistent, the system time is modified according to the preset time conversion configuration of the OS. Since the OS has a time zone definition for the RTC time, when the time zone of the RTC time is equal to the time zone defined by the time zone, the OS can execute the original steps, that is, the original time conversion configuration to convert the system time to obtain the real time.

Description

Technical Field

[0001] The present invention relates to the field of time synchronization, and in particular to a method for automatically synchronizing real time with an OS and related components thereof. Background Art

[0002] When the server leaves the factory, the RTC (Real-Time Clock) chip in the server will keep timing, which is called RTC time. The RTC time may be the local time in the time zone where the server is produced, or it may be the time in the zero time zone, that is, UTC (Universal Time Coordinated). The server will install the OS (operating system) according to the RTC time, and obtain the RTC time as the system time used during the operation of the OS. However, since different OSs have different time zone definitions for RTC time, for example, regardless of the time zone in which the RTC time is actually, the Linux OS will regard the RTC time as the UTC time. After obtaining the RTC time as the system time, the Linux OS will modify the system time according to its time zone definition for the RTC time. When the time zone of the RTC time is not actually the UTC time, the Linux OS will eventually obtain the wrong real time, resulting in the real time that the OS considers is not the real time required by the user. Summary of the invention

[0048] The core of the present invention is to provide a method for automatically synchronizing the real time of an OS and its related components, which can avoid modifying the system time into an erroneous real time to ensure that the real time considered by the OS is consistent with the real time required by the user.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Please refer to Figure 1 , Figure 1 A flowchart of a method for automatically synchronizing real time of a server OS provided in this application includes:

[0051] S11: Generate a corresponding time zone mark according to the time zone corresponding to the RTC time in the RTC chip;

[0052] When the server leaves the factory, the manufacturer will set an RTC time for the RTC chip, which can be the actual time corresponding to the time zone where the server is produced, that is, the local time, or the actual time corresponding to the zero time zone, that is, the UTC time. Considering that simply obtaining the RTC time cannot determine which time zone the RTC time specifically represents, the corresponding time zone mark can be generated in advance according to the time zone represented by the RTC time. For example, when the RTC time is represented as local time, the RTC_LOCAL=1 mark is generated to indicate that the RTC time is local time; when the RTC time is represented as UTC time, the RTC_LOCAL=0 mark is generated to indicate that the RTC time is UTC time.

[0053] S12: Use the RTC time as the OS system time;

[0054] In order to avoid the problem of inaccurate RTC time caused by directly modifying the RTC time, in this application, when the OS uses the RTC time, it first generates a copy of the RTC time, and uses the copy of the RTC time as the system time of the OS. Subsequent operations are all to modify the system time of the OS, and the RTC time in the RTC chip is not directly modified, thereby avoiding the problem of inaccurate RTC time.

[0055] S13: Determine whether the time zone corresponding to the time zone mark is consistent with the time zone corresponding to the time zone definition of the RTC time by the OS;

[0056] Considering that the time zone corresponding to the RTC time is different from the time zone definition of the RTC time by the OS, time errors may occur. For example, the Linux OS will regard the RTC time as the UTC time, but when the RTC time is actually the local time instead of the UTC time, the Linux OS is equivalent to regarding the local time as the UTC time, causing the subsequent Linux OS to process the local time as the UTC time, resulting in the actual time finally displayed on the OS not being the actual time required by the user; or the Linux OS itself can display the actual time required by the user, but the actual time of the OS of the virtual machine installed on the Linux OS has a display error. Therefore, before processing the system time, it is necessary to first determine whether the time zone corresponding to the time zone mark is consistent with the time zone corresponding to the time zone definition of the RTC time by the OS.

[0057] S14: If they are consistent, the system time is modified according to the preset time conversion configuration corresponding to the OS, and the modified system time is used as the actual time;

[0058] When the time zone corresponding to the time zone mark is consistent with the time zone corresponding to the time zone definition, it means that the system time can be converted into the real time only according to the original steps or procedures of the OS. For example, in the time zone definition of the Linux OS, the RTC time is defined as the UTC time, and the RTC time is actually the UTC time. When the Linux OS is in the East 8 time zone, the RTC time is obtained as the system time, and then 8 hours is added to the system time to get the time in the East 8 time zone, that is, the real time required by the user.

[0059] S15: If they are inconsistent, the system time is modified according to the preset time conversion configuration corresponding to the OS, and the modified system time is used as the actual time;

[0060] Among them, the OS includes at least Linux OS and Windows OS.

[0061] When the time zone corresponding to the time zone mark is inconsistent with the time zone corresponding to the time zone definition, in order to prevent the OS from converting the system time into an erroneous real time, a time conversion configuration can be set in advance for the OS. For example, when the OS is a Linux OS, the Linux OS defines the time zone of the RTC time as UTC time, but the RTC time is actually the local time, then the system time can be treated directly as the real time without any processing. It can be seen that when the OS is a Linux OS, when the time zone corresponding to the time zone mark is inconsistent with the time zone corresponding to the time zone definition, its preset time conversion configuration is not to modify the system time.

[0062] It should also be noted that when the OS is Windows OS or other OS with time zone defined as local time zone, the system time can be modified in a similar manner. For example, when the OS is Windows OS and the OS is located in the East 8 time zone, since Windows OS regards the RTC time as local time, when the RTC time is actually also the local time, the system time can be directly regarded as the real time. When the RTC time is UTC time, the system time can be modified according to the time difference between the East 8 time zone and the zero time zone, and the modified system time can be used as the real time. That is, the preset time conversion configuration in the case of Windows OS is to modify the system time according to the time difference between the East 8 time zone and the zero time zone.

[0063] In summary, a corresponding time zone mark is generated according to the time zone of the RTC time, and the RTC time is used as the system time of the OS. It is determined whether the time zone represented by the time zone mark is consistent with the time zone represented by the time zone definition of the OS. If they are consistent, the system time is converted into the real time according to the original time conversion configuration of the OS. If they are inconsistent, the system time is modified according to the preset time conversion configuration of the OS. Since the OS has a time zone definition for the RTC time, when the time zone of the RTC time is equal to the time zone defined by the time zone, the OS can execute the original steps, that is, the original time conversion configuration to convert the system time to obtain the real time. If they are not equal, the preset time conversion configuration is used to modify the system time to avoid modifying the system time to the wrong real time, so as to ensure that the final real time is consistent with the real time required by the user.

[0064] Based on the above embodiments:

[0065] As a preferred embodiment, before generating the corresponding time zone mark according to the type of the RTC time in the RTC chip, it also includes:

[0066] Determine whether the current time is connected to the cloud time synchronization server;

[0067] If yes, the time recorded in the cloud time synchronization server is used as the actual time;

[0068] If not, the process proceeds to the step of generating a corresponding time zone mark according to the type of the RTC time in the RTC chip.

[0069] In order to improve the efficiency of OS synchronization of real time, in this application, considering that the time recorded in the cloud time synchronization server must be the local time corresponding to the time zone where the OS time zone is defined, before generating the time zone mark, it can be determined whether the current moment is connected to the cloud time synchronization server. If it is normally connected to the cloud time synchronization server, the time recorded in the cloud time synchronization server is obtained. Since the time recorded in the cloud time synchronization server must be correct, it can be directly used as the real time. If it is disconnected from the cloud time synchronization server, the subsequent steps of generating the corresponding time zone mark according to the type of RTC time in the RTC chip are entered. It can be seen that before generating the time zone mark, first determining whether the current moment is connected to the cloud time synchronization server can improve the efficiency of OS synchronization of real time.

[0070] As a preferred embodiment, when the OS is Windows OS, the system time is modified according to the preset time conversion configuration corresponding to the OS, including:

[0071] determining the time difference between the zero time zone and the time zone corresponding to the time zone definition;

[0072] The sum of the system time and the time difference is taken as the modified system time.

[0073] In order to accurately modify the system time, in this application, since the time zone where the OS itself is located is pre-defined, and the time zone of the RTC time in Windows OS is defined as the local time zone, when the RTC time is UTC time, the difference between the system time and the real time is determined based on the time difference between the time zone where the OS itself is located and the zero time zone, and then the system time is added with the time difference to obtain the real time required by the user. For example, when the Windows OS itself is located in the East 8 time zone and the RTC time is UTC time, it can be known that the East 8 time zone and the zero time zone are 8 hours apart, and the time difference is determined to be 8 hours. The system time plus the time after 8 hours is the real time in the East 8 time zone. It can be seen that the system time can be accurately modified based on the time difference to obtain accurate real time.

[0074] As a preferred embodiment, when the OS is a Linux OS, the system time is converted into the real time according to the original time conversion configuration of the OS, including:

[0075] Set the isutc configuration in OS to the effective configuration;

[0076] Use isutc configuration to convert RTC time to real time.

[0077] In order to accurately modify the system time, in this application, considering that some OS such as Linux OS have isutc configuration, in which the system time can be converted into real time through specific logic, when the RTC time is actually local time, although the isutc configuration will make mistakes in converting the system time, when the RTC time is actually UTC time, the isutc configuration can accurately convert the system time into real time. Specifically, it is possible to first determine whether the RTC time is UTC time according to the time zone identifier corresponding to the RTC time, and automatically modify the isutc configuration according to the judgment result. When the RTC time is UTC time, the isutc configuration in the time zone configuration of the OS can be set to valid, otherwise the isutc configuration is set to invalid, so that the isutc configuration works at the right time. Further, the step of determining whether the RTC time is UTC time can be performed during the installation of the OS, and the isutc configuration is installed when the RTC time is UTC time. If the RTC time is local time, the isutc configuration is not installed, which is equivalent to removing the isutc configuration from the OS to improve efficiency. It can be seen that by setting the isutc configuration, the system time can be accurately modified.

[0078] As a preferred embodiment, after generating the corresponding time zone mark according to the type of the RTC time in the RTC chip, it also includes:

[0079] Send time zone stamp to PNOR;

[0080] Determine whether the time zone corresponding to the time zone mark is consistent with the time zone corresponding to the time zone definition of the RTC time by the OS, including:

[0081] Determine whether the time zone corresponding to the time zone tag stored in PNOR is consistent with the time zone corresponding to the time definition of the RTC time by the OS;

[0082] If the time zone corresponding to the time zone tag stored in PNOR is consistent with the time zone corresponding to the time definition of the RTC time by the OS, it is determined to be consistent;

[0083] If the time zone corresponding to the time zone mark stored in PNOR is inconsistent with the time zone corresponding to the time definition of the RTC time by the OS, it is determined to be inconsistent.

[0084] In order to improve the efficiency of OS synchronization of real time, in this application, considering that OS itself will not record the time zone mark in the RTC chip, if the time zone mark is stored in the RTC chip, since the steps of OS reading data in the RTC chip are relatively cumbersome, it is necessary to enter the OS interface and use specific instructions to read the time zone mark in the RTC chip, which makes the efficiency of OS synchronization of real time slower; in addition, it is also considered that OS may not be in an online state and cannot obtain the real time from the time synchronization server in the cloud. Therefore, the time zone mark can be stored in the firmware layer outside the OS, such as in PNOR (PNOR flash memory, PNOR flash memory), so as to directly call the time zone mark stored in PNOR, without the need to use specific instructions to read, in the absence of network and time synchronization server, as long as the RTC initial time setting and the time zone mark stored in PNOR are correct, then the real time finally displayed by the OS is the real time required by the user. It can be seen that storing the time zone mark in PNOR can not only improve the efficiency of OS synchronization of real time, but also ensure that the OS obtains the correct real time when the OS is not online.

[0085] As a preferred embodiment, before generating a corresponding time zone mark according to the time zone corresponding to the RTC time in the RTC chip, it also includes:

[0086] According to the user's instruction, the time zone corresponding to the RTC time is modified to the time zone corresponding to the user's instruction.

[0087] In order to modify the time zone corresponding to the RTC time, in this application, it is taken into account that the user may change the OS during use. When the user changes the OS, due to the different time definitions of the OS, the new OS may convert the RTC time into the wrong real time. Therefore, after the user changes the new OS, it is necessary to match the time zone corresponding to the RTC time with the new OS. Since the time zone definition of the new OS is known, a user instruction can be generated according to the time zone definition of the OS to modify the time zone corresponding to the RTC time. For example, when the new OS is a Linux OS, the time zone corresponding to the RTC time can be set to UTC time through the "#timedatectl set-rtc-local 0" instruction. Furthermore, in addition to modifying the original corresponding RTC time and the corresponding configuration file, the time zone mark of the RTC time can also be updated. It can be seen that the time zone corresponding to the RTC time can be modified well according to the user instruction.

[0088] As a preferred embodiment, when the OS is a Linux OS, the system time is modified according to a preset time conversion configuration corresponding to the OS, including:

[0089] Set the isutc configuration in the OS to an invalid configuration;

[0090] Use system time as real time.

[0091] In order to obtain accurate real time, in this application, considering that some OS such as Linux OS have isutc configuration, in which the system time can be converted into real time through specific logic, but when the RTC time is actually the local time, the isutc configuration will make an error when converting the system time. For example, please refer to Figure 2 , Figure 2 A schematic diagram of the principle of generating confusion of real time provided for this application, because Linux OS will regard RTC time as UTC time for its time definition of RTC time, but when RTC time is actually local time, it is equivalent to OS regarding local time as UTC time, if isutc is configured as a valid configuration, it will convert UTC time into local time, that is, convert system time into real time, but because the system time here is actually local time, it is equivalent to converting local time to obtain another wrong local time, so the obtained time is also wrong, and finally when the user finds that the real time is the wrong time, the wrong real time needs to be modified to be converted into the correct real time, it can be seen that the system time needs to jump several times before it can become the correct real time. Based on this, the isutc configuration can be set to an invalid configuration to avoid OS modifying the system time, and the system time can be directly used as the real time. It can be seen that by setting the isutc configuration to an invalid configuration, accurate real time can be obtained.
