  2. Timestamp - Wikipedia

    en.wikipedia.org/wiki/Timestamp

    A timestamp is a sequence of characters or encoded information identifying when a certain event occurred, usually giving date and time of day, sometimes accurate to a small fraction of a second. Timestamps do not have to be based on some absolute notion of time, however.

  3. Snowflake ID - Wikipedia

    en.wikipedia.org/wiki/Snowflake_ID

    Instagram uses a modified version of the format, with 41 bits for a timestamp, 13 bits for a shard ID, and 10 bits for a sequence number. [8] Mastodon's modified format has 48 bits for a millisecond-level timestamp, as it uses the UNIX epoch. The remaining 16 bits are for sequence data. [9]

  4. Template:Timestamp - Wikipedia

    en.wikipedia.org/wiki/Template:Timestamp

    is the template equivalent for the magic word (also known as variable) {{CURRENTTIMESTAMP}}. The template invokes this variable when called. Due to MediaWiki and browser caching, these variables frequently show when the page was cached rather than the current time.

  5. Universally unique identifier - Wikipedia

    en.wikipedia.org/wiki/Universally_unique_identifier

    UUIDv7 begins with a 48 bit big-endian Unix Epoch timestamp with approximately millisecond granularity. The timestamp can be shifted by any time shift value. Directly after the timestamp follows the version nibble, that must have a value of 7. The variant bits have to be 10x. Remaining 74 bits are random seeded counter (optional, at least 12 ...

  6. Unix time - Wikipedia

    en.wikipedia.org/wiki/Unix_time

    Unix time is also used as a mechanism for storing timestamps in a number of file systems, file formats, and databases. The C standard library uses Unix time for all date and time functions, and Unix time is sometimes referred to as time_t, the name of the data type used for timestamps in C and C++ .

  7. Timestamping (computing) - Wikipedia

    en.wikipedia.org/wiki/Timestamping_(computing)

    In computing, timestamping refers to the use of an electronic timestamp to provide a temporal order among a set of events. Timestamping techniques are used in a variety of computing fields, from network management and computer security to concurrency control .

  8. Time formatting and storage bugs - Wikipedia

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

    Many existing file formats, communications protocols, and application interfaces employ a variant of the Unix time_t date format, storing the number of seconds since the Unix Epoch (midnight UTC, 1 January 1970) as an unsigned 32-bit binary integer. This value will roll over on 7 February 2106 at 06:28:16 UTC.
