This invention relates generally to a method and apparatus for timely forwarding, discarding, and delivering data packets over the network and to their destination nodes and the optimization of data transfer throughput through the network. The timely forwarding and discarding are possible thanks to the standard global common time reference (CTR) that is known as UTC (Coordinated Universal Time). UTC is available from GPS (Global Positioning System), Galileo, and GLONASS (Global Navigation Satellite System). Data transfer throughput optimization is pursued by taking advantage of the timely forwarding and discarding properties to improve the data packets transfer flow control mechanisms, such as the sliding window re-sizing algorithm implemented by the widely deployed Transmission Control Protocol (TCP).

A system and method are disclosed for automatically converting dates and times in electronic text messages to the local dates and times of the message recipients. For example, when a text message is sent to an intended recipient, a messaging server can recognize date and time strings in the message text string, if any. The server can parse the date / time information into Coordinated Universal Time (“UTC”) form. The server also receives locale and time zone information from the intended recipient's client application, and can send this information to the originating client application. The originating client application can use this locale and time zone information to convert the UTC date / time information from the message string, if any, to the localized date and time of the message recipient. The localized date / time information is inserted into the message string, and the resulting message is forwarded to the recipient. As an option, the original message string may also be conveyed to the recipient for verification purposes.

The invention relates to an analog display watch that comprises two separate time displays (40, 44) for a first and second time zone, and a time zone indicator (50) comprising a place ring (53) associated with two counters (51, 52) that are angularly offset by 1 / 24 of a turn, one of which is used in combination with Standard Time and the other with Daylight Savings Time (DST). A primary manual time set device (31) enables the first and second time displays (40, 44) to be set separately. A second manual time set device allows the entire device to turn the second time display (44) and the time zone indicator (50) together step by step without modifying the status of the first time display (40). A manual corrector (34, 63) enables the place ring (53) to turn step by step without modifying the status of the first and second time displays (40 and 44). Place symbols (54) are distributed on the circumference of the place ring (53) with a step of a 1 / 96 turn, such that the place symbols (54) include symbols (54a, 54b) that represent time zones that differ by a number of hours that is not a whole number relative to Coordinated Universal Time (UTC). With these characteristics, simple manipulations will enable the time at any place in the world to be displayed, and changes to time zones to be made easily, taking into account Daylight Savings Time and a change of hemisphere, if applicable.

The present invention is a low-cost timing and synchronization method and equipment for a global positioning system receiver, which relates to the field of time granting and synchronization, and in particular to a baseband processing chip based on a global positioning system, such as the global positioning system (GPS) of the United States. Low-cost timing and synchronization domains implemented at the level. The invention improves the timing and synchronization method based on the global positioning system, and realizes it based on the global positioning system baseband processing chip device. The invention performs soft calibration on the crystal oscillator through the coordinated universal time calculated by the global positioning system, realizes time service to external equipment through the combination of time code and synchronous pulse signal, and uses low-cost crystal oscillator to realize high-precision time service. At the same time, the invention does not need to calibrate the crystal oscillator in the form of hardware, greatly simplifies the system design, reduces the cost, and has the advantages of small hardware overhead, strong scalability, and high reliability.

An operating system in a virtual environment can obtain the current time of the processor that the OS is utilizing through a method for synchronizing timers on multiple processors with a standard reference time, such as the Coordinated Universal Time (UTC). A hypervisor controlling the processors obtains a number of synchronization values that, together with a local timer counter value, are utilized by the guest operating system to determine the physical processor time.

A method for synchronizing times across a plurality of base stations in a frequency division duplexing (FDD) wireless communications network includes receiving, at a plurality of base stations in the network, at least one timing reference signal associated with an external time reference, comparing the timing reference signal to internal clock times of the plurality of base stations, receiving an instruction to perform an activity at a time relative to Coordinated Universal Time (UTC), and performing the activity, by the plurality of base stations, at the time relative to UTC.

Exemplary method, system, and computer program embodiments for establishing an applicable local time zone of a web browser in a computing environment are provided. In one such embodiment, a plurality of time zone offsets is queried over a predetermined period of time to obtain a listing of possible time zones. Ones of the listing of possible time zones matching a polled absolute coordinated universal time (UTC) offset are selected. A plurality of weights are assigned to the selected ones of the listing of possible time zones based on at least one of the matching polled absolute UTC offset, a matching daylight savings observance type, a matching Hyper-Text Transfer Protocol (HTTP) accept-language header and a human population size. The listing of possible time zones is sorted based on the plurality of assigned weights.
