TIME(2)			   Linux Programmer's Manual		       TIME(2)

NAME
       time - get time in seconds

SYNOPSIS
       #include	<time.h>

       time_t time(time_t *t);

DESCRIPTION
       time  returns the time since the	Epoch (00:00:00	UTC, January 1,	1970),
       measured	in seconds.

       If t is non-NULL, the return value is also stored in the	memory pointed
       to by t.

RETURN VALUE
       On  success,  the value of time in seconds since	the Epoch is returned.
       On error, ((time_t)-1) is returned, and errno is	set appropriately.

ERRORS
       EFAULT t	points outside your accessible address space.

NOTES
       POSIX.1 defines seconds since the Epoch as a value to be	interpreted as
       the number of seconds between a specified time and the Epoch, according
       to a formula for	conversion from	UTC equivalent to  conversion  on  the
       naive  basis that leap seconds are ignored and all years	divisible by 4
       are leap	years.	This value is not the same as  the  actual  number  of
       seconds between the time	and the	Epoch, because of leap seconds and be-
       cause clocks are	not required to	be synchronised	to a  standard	refer-
       ence.   The  intention  is that the interpretation of seconds since the
       Epoch values be consistent; see POSIX.1 Annex B 2.2.2 for  further  ra-
       tionale.

CONFORMING TO
       SVr4, SVID, POSIX, X/OPEN, BSD 4.3
       Under  BSD  4.3,	this call is obsoleted by gettimeofday(2).  POSIX does
       not specify any error conditions.
