#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;
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 Daylight Saving time applies locally during the appropriate part of the year.
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.
