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



NAME
       time - get time in seconds

SYNOPSIS
       #include 

       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  conver-
       sion  on	 the na??ve 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 because clocks are not required to be synchronised to
       a  standard  reference.	 The  intention is that the interpretation of
       seconds since the Epoch values be  consistent;  see  POSIX.1  Annex  B
       2.2.2 for further rationale.

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.
