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       This function is obsolete.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

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