NAME

       ftime - return date and time

LIBRARY

       Standard C library (libc, -lc)

SYNOPSIS

       #include <sys/timeb.h>

       int ftime(struct timeb *tp);

DESCRIPTION

       NOTE: This function is no longer provided by 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.)

HISTORY

       Removed in glibc 2.33.  4.2BSD, POSIX.1-2001.  Removed in POSIX.1-2008.

       This  function  is  obsolete.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.
