NAME

       ftime - return date and time

SYNOPSIS

       #include <sys/timeb.h>

       int ftime(struct timeb *tp);

DESCRIPTION

       NOTE:  This  function  is deprecated, and will be removed in a future version of the GNU C
       library.  Use clock_gettime(2) instead.

       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       This function is obsolete.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

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