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	 time-
       zone  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 sys-
       tems document, a -1 error return.)

ATTRIBUTES
       For  an	explanation  of	 the  terms  used   in	 this	section,   see
       attributes(7).

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       This function is obsolete.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  suf-
       fices,	time(2)	 can  be  used;	 gettimeofday(2)  gives	 microseconds;
       clock_gettime(2) gives nanoseconds but is not as widely available.

BUGS
       Early glibc2 is buggy and returns 0 in the millitm field;  glibc	 2.1.1
       is correct again.
