FTIME(3)



FTIME(3)                   Linux Programmer's Manual                  FTIME(3)

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

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       This  function is obsolete.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.
