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 Return current date and time 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, millitm is the num- ber of milliseconds since time seconds since the epoch, timezone is the local time zone measured in minutes of time west of Greenwich, and dst- flag is a flag that, if non-zero, indicates that Daylight Saving time applies locally during the appropriate part of the year.

These days the contents of the timezone and dstflag fields are unde- fined.

RETURN VALUE This function always returns 0.

BUGS This function is obsolete.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.

HISTORY The ftime() function appeared in 4.2BSD.
