It doesn't. From http://en.wikipedia.org/wiki/Unix_time:

	Unix time, or 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,[note 1] not counting leap seconds.[note 2] It is used
	widely in Unix-like and many other operating systems and file
	formats. Due to its handling of leap seconds, it is neither a
	linear representation of time nor a true representation of
	UTC.[note 3] Unix time may be checked on most Unix systems by
	typing date +%s on the command line.
