FTIME(3)                                            Linux Programmer's Manual                                           FTIME(3)



NAME
       ftime - return date and time

SYNOPSIS
       #include <sys/timeb.h>

       int ftime(struct timeb *tp);

DESCRIPTION
       This function returns the current time as seconds and milliseconds since the Epoch, 1970-01-01 00:00:00 +0000 (UTC).  The
       time is returned in tp, which is declared as follows:

           struct timeb {
               time_t         time;
               unsigned short millitm;
               short          timezone;
               short          dstflag;
           };

       Here time is the number of seconds since the Epoch, and millitm is the number of milliseconds since  time  seconds  since
       the Epoch.  The timezone field is the local timezone measured in minutes of time west of Greenwich (with a negative value
       indicating minutes east of Greenwich).  The dstflag field is a flag that, if nonzero, indicates that Daylight Saving time
       applies locally during the appropriate part of the year.

       POSIX.1-2001 says that the contents of the timezone and dstflag fields are unspecified; avoid relying on them.

RETURN VALUE
       This function always returns 0.  (POSIX.1-2001 specifies, and some systems document, a -1 error return.)

CONFORMING TO
       4.2BSD, POSIX.1-2001.  POSIX.1-2008 removes the specification of ftime().

       This  function  is  obsolete.  Don't use it.  If the time in seconds suffices, time(2) can be used; gettimeofday(2) gives
       microseconds; clock_gettime(2) gives nanoseconds but is not as widely available.

BUGS
       Under libc4 and libc5 the millitm field is meaningful.  But early glibc2 is buggy and returns 0  there;  glibc  2.1.1  is
       correct again.
