!!! Overview
[{$pagename}] (also known as [POSIX time]) is a system for describing instants in [time], defined as the number of [seconds] that have elapsed since 00:00:00 [Coordinated Universal Time] ([UTC]), Thursday, 1 January [1970|Year 1970] not counting [leap seconds]. (ie the [Unix Epoch])[{$pagename}] is a [DateTime] and a [NumericDate]
[{$pagename}] is used widely in [UNIX]-like and many other [Operating Systems] and file formats. Because it does not handle [leap seconds], it is neither a linear representation of time nor a true representation of [UTC].
[{$pagename}] may be checked on most [UNIX] [Operating Systems] by typing date +%s on the [command-line].
!! [{$pagename}] [Overflow|Buffer overflow]
At 03:14:08 UTC on January 19, [2038|Year 2038] (+231), a 32-[bit] [Signed int] representation of [Unix time will overflow|2,147,483,647]. Systems using a 32-bit signed integer [{$pagename}] will therefore be unable to represent that time, or any later, and will likely wrap around to 20:45:52 UTC on December 13, [1901|Year 1901], with integer value -231. This is a [NumericDate]!! More Information
