  2. 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]

  3. Year 2038 problem - Wikipedia

    en.wikipedia.org/wiki/Year_2038_problem

    Many computer systems measure time and date using Unix time, an international standard for digital timekeeping. Unix time is defined as the number of seconds elapsed since 00:00:00 UTC on 1 January 1970 (an arbitrarily chosen time based on the creation of the first Unix system ), which has been dubbed the Unix epoch .

  4. Timestamp - Wikipedia

    en.wikipedia.org/wiki/Timestamp

    The term "timestamp" derives from rubber stamps used in offices to stamp the current date, and sometimes time, in ink on paper documents, to record when the document was received. Common examples of this type of timestamp are a postmark on a letter or the "in" and "out" times on a time card .

  5. Unix time - Wikipedia

    en.wikipedia.org/wiki/Unix_time

    A signed 32-bit value covers about 68 years before and after the 1970-01-01 epoch. The minimum representable date is Friday 1901-12-13, and the maximum representable date is Tuesday 2038-01-19. One second after 2038-01-19T03:14:07Z this representation will overflow in what is known as the year 2038 problem.

    Timestamp attribute helps to identify when an event occurred. Subject ID is an encoded-by-algorithm ID, that has been extracted out of a cookie . Raw Data includes information straight from the data provider without being processed by an algorithm nor human.

  7. System time - Wikipedia

    en.wikipedia.org/wiki/System_time

    System time is measured by a system clock, which is typically implemented as a simple count of the number of ticks that have transpired since some arbitrary starting date, called the epoch. For example, Unix and POSIX -compliant systems encode system time (" Unix time ") as the number of seconds elapsed since the start of the Unix epoch at 1 ...

    As of 21 January 2025 (two months after PHP 8.4's release), PHP is used as the server-side programming language on 75.0% of websites where the language could be determined; PHP 7 is the most used version of the language with 47.1% of websites using PHP being on that version, while 40.6% use PHP 8, 12.2% use PHP 5 and 0.1% use PHP 4.

  9. 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 ...
