Use <A HREF="/man2/clock_gettime">clock_gettime(2)</A> 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 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 For an explanation of the terms used in this section, see at- <A HREF="/man7/tributes">tributes(7)</A>. +----------+---------------+---------+ |Interface | Attribute | Value | +----------+---------------+---------+ |ftime() | Thread safety | MT-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 This function is obsolete.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, <A HREF="/man2/time">time(2)</A> can be used; <A HREF="/man2/gettimeofday">gettimeofday(2)</A> gives microseconds; <A HREF="/man2/clock_gettime">clock_gettime(2)</A> 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.
