Problems solved by technology

Using time synchronization software, when Coordinated Universal Time (UTC) performs leap seconds, because there is no unified leap second processing method, the time is not adjusted at the same time, which affects the normal operation of the time synchronization system

Embodiment 1

[0034] The inventive method comprises following two processes:

[0035] 1. Input the atomic time and leap second forecast, and output the correct UTC time;

[0036] 2. Input UTC time and leap second forecast, and output correct atomic time.

[0037] Among them, the input is atomic time and leap second forecast, and the output is coordinated universal time. The process includes the following steps:

[0038] ① Obtain the leap second forecast from the satellite navigation message. The leap second forecast includes the current time difference between UTC and atomic time, the future time difference between UTC and atomic time, and the absolute second of UTC. It should be noted that since the leap second forecast is calibrated by the UTC time system, and the input atomic information is calibrated by the atomic time system, the two time systems use different reference systems, so the two systems need to be calibrated For information conversion, the time correspondence between the t...

Embodiment 2

[0054] This embodiment mainly adds the following special processing steps in the process step ⑤ in which the input of embodiment 1 is the atomic time and the leap second forecast, and the output is the coordinated universal time: that is, if the current moment is the occurrence of the leap second, the output will appear In the case of 60 seconds in UTC, special processing is required at this time, that is, output 60 seconds before the leap second occurs, that is, set 60 to the second of the obtained Coordinated Universal Standard Time, so as to obtain the correct leap second time Coordinated Universal Time standard time.

[0055] Other technical characteristics are identical with embodiment 1.

Embodiment 3

[0057] This embodiment mainly adds the following special processing steps in the process step v) in which the input of embodiment 1 is Coordinated Universal Time and leap second forecast, and the output is atomic time: that is, if the current moment is neither before the leap second occurs, nor If it is not after a leap second occurs, that is, when a positive leap second occurs, and 60 seconds in UTC is entered, it is necessary to judge whether the second in UTC is 60; if the second in UTC is 60, the UTC absolute Seconds plus the current time difference between UTC and atomic time to get the absolute second of atomic time; if the second of UTC standard time is not 60, add the absolute second of UTC to the future time difference between UTC and atomic time to get atomic time Absolute seconds.

[0058] Other technical characteristics are identical with embodiment 1.

Abstract

The invention discloses a time service time leap second processing method, which includes two processes: the input is atomic time and leap second forecast, the output is coordinated universal time, and the input is coordinated universal time and leap second forecast, and the output is atomic time. The present invention adopting the above-mentioned technical scheme provides the conversion from UTC to atomic time, and the conversion from atomic time to UTC. The two time system conversion methods ensure that the systems using UTC and atomic time can be synchronized and unified at the time when the leap second occurs. Avoid the impact of leap seconds on time synchronization and ensure the normal operation of the time synchronization system.

Description

technical field [0001] The invention belongs to the field of time synchronization of time service, and in particular relates to a processing method for converting from atomic time to universal time and from universal time to atomic time system, that is, a time service time leap second processing technology. Background technique [0002] In the world time system, Coordinated Universal Time (UTC) is the most widely used in people's production and life. [0003] The time based on the rotation of the earth is called universal time. However, because the rotation of the earth is not stable, it will be affected by factors such as the precession of the rotation axis, the friction of the lunar tide, and seasonality, so the universal time is not a uniform time scale. Based on the atomic oscillation period, the time scale produced by the World Bureau of Weights and Measures with the weighted average of atomic clocks in various national laboratories around the world is called Internati...
