Analysis of information sources in references of the Wikipedia article "Unix time" in English language version.
This timestamp is represented as the number of nanoseconds since January 1, 1970 at 0:00 UTC, disregarding leap seconds
time returns the time since 00:00:00, Jan. 1, 1971, measured in sixtieths of a second.
time returns the time since 00:00:00, Jan. 1, 1972, measured in sixtieths of a second...The time is stored in 32 bits. This guarantees a crisis every 2.26 years.
The GNU C Library project provides the core libraries for the GNU system and GNU/Linux systems, as well as many other systems that use Linux as the kernel.
The tz code and data support leap seconds via an optional "right" configuration where a computer's internal time_t integer clock counts every TAI second, as opposed to the default "posix" configuration where the internal clock ignores leap seconds. The two configurations agree for timestamps starting with 1972-01-01 00:00:00 UTC (time_t 63 072 000) and diverge for timestamps starting with time_t 78 796 800, which corresponds to the first leap second 1972-06-30 23:59:60 UTC in the "right" configuration, and to 1972-07-01 00:00:00 UTC in the "posix" configuration.
Attributes: year, month, day, hour, minute, second, microsecond, and tzinfo.
Time is stored in Unix time_t format if this flags [sic] is set and in Windows FILETIME format otherwise
