  2. Network Time Protocol - Wikipedia

    en.wikipedia.org/wiki/Network_Time_Protocol

    The network time server in Windows 2000 Server (and Windows XP) does not implement NTP disciplined synchronization, only locally disciplined synchronization with NTP/SNTP correction. [44] Beginning with Windows Server 2003 and Windows Vista, the NTP provider for W32Time became compatible with a significant subset of NTPv3. [45]

  4. ntpd - Wikipedia

    en.wikipedia.org/wiki/Ntpd

    The ntpd program is an operating-system daemon that sets and maintains a computer system's system time in synchronization with Internet-standard time servers.It is a complete implementation of the Network Time Protocol (NTP) version 4, but retains compatibility with versions 1, 2, and 3 as defined by RFC 1059, RFC 1119, and RFC 1305, respectively. ntpd performs most computations in 64-bit ...

  5. Clock synchronization - Wikipedia

    en.wikipedia.org/wiki/Clock_synchronization

    Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks.Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates.

  6. Timing synchronization function - Wikipedia

    en.wikipedia.org/wiki/Timing_synchronization...

    Timing synchronization is achieved by stations periodically exchanging timing information through beacon frames. In (intra) BSS, the AP sends the TSF information in the beacons. In Independent Basic Service Set (IBSS, ad-hoc), each station competes to send the beacon.

    This can also be seen in Internet Explorer 7/8 on Windows XP and Windows Server 2003. Image toolbar has been removed. Most of the commands that were on this floating toolbar – Save Picture, E-mail Picture, Set as Background, etc. – are now in the context menu that appears when an image is right-clicked.

  8. Time formatting and storage bugs - Wikipedia

    en.wikipedia.org/wiki/Time_formatting_and...

    On 5 January 1975, the 12-bit field that had been used for dates in the TOPS-10 operating system for DEC PDP-10 computers overflowed, in a bug known as "DATE75". The field value was calculated by taking the number of years since 1964, multiplying by 12, adding the number of months since January, multiplying by 31, and adding the number of days since the start of the month; putting 2 12 − 1 ...

  9. Synchronization - Wikipedia

    en.wikipedia.org/wiki/Synchronization

    Synchronization is the coordination of events to operate a system in unison. For example, the conductor of an orchestra keeps the orchestra synchronized or in time. Systems that operate with all parts in synchrony are said to be synchronous or in sync—and those that are not are asynchronous.
