FTIME(3) Library Functions Manual FTIME(3)

ftime — get date and time

#include <sys/timeb.h>

int
ftime(struct timeb *tp);

This interface is obsoleted by gettimeofday(2).

The () routine fills in a structure pointed to by its argument, as defined by ⟨sys/timeb.h⟩:

/*
 * Structure returned by ftime system call
 */
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.

#include <sys/types.h> #include <sys/timeb.h>

The include file <sys/types.h> is necessary.

gettimeofday(2), settimeofday(2), ctime(3), time(3), compat(5)

The ftime function appeared in 4.2BSD.
