TIME(3V) C LIBRARY FUNCTIONS TIME(3V)
NAME
time, ftime - get date and time
SYNOPSIS
#include <sys/types.h>
#include <sys/time.h>
time_t time(tloc)
time_t *tloc;
#include <sys/timeb.h>
int ftime(tp)
struct timeb *tp;
DESCRIPTION
time() returns the time since 00:00:00 GMT, Jan. 1, 1970,
measured in seconds.
If tloc is non-NULL, the return value is also stored in the
location to which tloc points.
ftime() fills in a structure pointed to by tp, as defined in
<sys/timeb.h>:
struct timeb
{
time_t time;
unsigned short millitm;
short timezone;
short dstflag;
};
The structure contains the time since the epoch in seconds,
up to 1000 milliseconds of more-precise interval, the local
time zone (measured in minutes of time westward from
Greenwich), and a flag that, if nonzero, indicates that Day-
light Saving time applies locally during the appropriate
part of the year.
RETURN VALUES
time() returns the value of time on success. On failure, it
returns (time_t) -1.
On success, ftime() returns no useful value. On failure, it
returns -1.
