FTIME(3) Linux Programmers Manual FTIME(3)
NAME
ftime - return date and time
SYNOPSIS
#include
int ftime(struct timeb *tp);
DESCRIPTION
This function returns the current time, in seconds and milliseconds
since the Epoch (00:00:00 UTC, 1 January 1970). 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 time zone 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 non-zero, 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.)
CONFORMING TO
4.2BSD, POSIX.1-2001.
BUGS
This function is obsolete. Dont use it. If the time in seconds suf
fices, time(2) can be used; gettimeofday(2) gives microseconds;
clock_gettime(3) gives nanoseconds but is not yet widely available.
Under libc4 and libc5 the millitm field is meaningful. But early
glibc2 is buggy and returns 0 there; glibc 2.1.1 is correct again.
