+.SH NAME
+ftime \- return date and time
+.SH LIBRARY
+Standard C library
+.RI ( libc ", " \-lc )
+.SH SYNOPSIS
+.nf
+.B "#include <sys/timeb.h>"
+.P
+.BI "int ftime(struct timeb *" tp );
+.fi
+.SH DESCRIPTION
+.BR NOTE :
+This function is no longer provided by the GNU C library.
+Use
+.BR clock_gettime (2)
+instead.
+.P
+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
+.IR tp ,
+which is declared as follows:
+.P
+.in +4n
+.EX
+struct timeb {
+ time_t time;
+ unsigned short millitm;
+ short timezone;
+ short dstflag;
+};
+.EE
+.in
+.P
+Here \fItime\fP is the number of seconds since the Epoch,
+and \fImillitm\fP is the number of milliseconds since \fItime\fP
+seconds since the Epoch.
+The \fItimezone\fP field is the local timezone measured in minutes
+of time west of Greenwich (with a negative value indicating minutes
+east of Greenwich).
+The \fIdstflag\fP field
+is a flag that, if nonzero, indicates that Daylight Saving time
+applies locally during the appropriate part of the year.
+.P
+POSIX.1-2001 says that the contents of the \fItimezone\fP and \fIdstflag\fP
+fields are unspecified; avoid relying on them.
+.SH RETURN VALUE
+This function always returns 0.
+(POSIX.1-2001 specifies, and some systems document, a \-1 error return.)
+.SH ATTRIBUTES
+For an explanation of the terms used in this section, see
+.BR attributes (7).

+.SH STANDARDS
+None.
+.SH HISTORY
+Removed in glibc 2.33.
+4.2BSD, POSIX.1-2001.
+Removed in POSIX.1-2008.
+.P
+This function is obsolete.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 (2)
+gives nanoseconds but is not as widely available.
+.SH BUGS
+Early glibc2 is buggy and returns 0 in the
+.I millitm
+field;
+glibc 2.1.1 is correct again.
+.\" .SH HISTORY
