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 Green-
       wich).  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       This  function  is  obsolete.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.
