ftime — return date and time
#include <sys/timeb.h>
int
ftime( |
struct timeb *tp); |
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.
This function always returns 0. (POSIX.1-2001 specifies, and some systems document, a −1 error return.)
For an explanation of the terms used in this section, see attributes(7).

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This function is obsolete.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.
