FTIME

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 fItimefP is the number of seconds since the epoch, fImillitmfP is the number of milliseconds since fItimefP seconds since the epoch, fItimezonefP is the local time zone measured in minutes of time west of Greenwich, and fIdstflagfP is a flag that, if nonzero, indicates that Daylight Saving time applies locally during the appropriate part of the year.

These days the contents of the fItimezonefP and fIdstflagfP fields are undefined.  

RETURN VALUE

This function always returns 0.  

BUGS

This function is obsolete.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(3) gives nanoseconds but is not yet widely available.

Under libc4 and libc5 the fImillitmfP 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.  

CONFORMING TO

BSD 4.2, POSIX 1003.1-2001.
