.TH FTIME 3 2001-12-14 "Linux" "Linux Programmer's Manual"
.SH NAME
ftime \- return date and time
.SH SYNOPSIS
.B "#include <sys/timeb.h>"
.sp
.BI "int ftime(struct timeb *" tp );
.SH DESCRIPTION
Return current date and time in
.IR tp ,
which is declared as follows:
.sp
.in +0.5i
.nf
struct timeb {
time_t time;
unsigned short millitm;
short timezone;
short dstflag;
};
.fi
.in -1i
.LP
Here \fItime\fP is the number of seconds since the epoch,
\fImillitm\fP is the number of milliseconds since \fItime\fP
seconds since the epoch, \fItimezone\fP is the local time zone
measured in minutes of time west of Greenwich, and \fIdstflag\fP
is a flag that, if non-zero, indicates that Daylight Saving time
applies locally during the appropriate part of the year.
.LP
These days the contents of the \fItimezone\fP and \fIdstflag\fP
fields are undefined.
.SH "RETURN VALUE"
This function always returns 0.
.SH "CONFORMING TO"
4.2BSD, POSIX.1-2001.
.SH BUGS
This function is obsolete.
Don't use it.
If the time in seconds
suffices,
.BR time (2)
can be used;
.BR gettimeofday (2)
gives microseconds;
.BR clock_gettime (3)
gives nanoseconds but is not yet widely available.
.LP
Under libc4 and libc5 the \fImillitm\fP field is meaningful.
But early glibc2 is buggy and returns 0 there;
glibc 2.1.1 is correct again.
.\" .SH HISTORY
.\" The
.\" .BR ftime ()
.\" function appeared in 4.2BSD.
.SH "SEE ALSO"
.BR gettimeofday (2),
.BR time (2)
