       ftime - return date and time

       #include <sys/timeb.h>

       int ftime(struct timeb *tp);

       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.

       This function always returns 0.	(POSIX.1-2001 specifies, and some sys‐
       tems document, a -1 error return.)

   Multithreading (see pthreads(7))
       The ftime() function is thread-safe.

       4.2BSD,	POSIX.1-2001.	POSIX.1-2008  removes  the  specification   of

       This  function is obsolete.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.

       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.
