TIME(2) System Calls Manual TIME(2)
NAME
time, ftime - get date and time
SYNOPSIS
long time((long *)0)
long time(tloc)
long *tloc;
#include <sys/types.h>
#include <sys/timeb.h>
ftime(tp)
struct timeb *tp;
DESCRIPTION
Time returns the time since the epoch 00:00:00 GMT, Jan. 1, 1970, mea-
sured in seconds.
If tloc is nonnull, the return value is also stored in the place to
which tloc points.
Ftime stores a more accurate time and other horological data in the
structure pointed to by tb:
struct timeb
{
time_t time; time since the epoch in seconds
unsigned short millitm; up to 1000 milliseconds of more-precise interval
short timezone; local time zone measured in minutes of time
westward from Greenwich
short dstflag; if nonzero, daylight saving time applies locally
during the appropriate part of the year
};
SEE ALSO
date(1), stime(2), ctime(3)
DIAGNOSTICS
ftime: EFAULT
BUGS
If the argument to time is bogus, the user program gets a memory fault
rather than an EFAULT.
