.Sh NAME
.Nm ftime
.Nd get date and time
.Sh LIBRARY
.Lb libcompat
.Sh SYNOPSIS
.In sys/types.h
.In sys/timeb.h
.Ft int
.Fn ftime "struct timeb *tp"
.Sh DESCRIPTION
.Bf -symbolic
This interface is obsoleted by
.Xr gettimeofday 2 .
.Ef
.Pp
The
.Fn ftime
routine fills in a structure pointed to by its argument,
as defined by
.In sys/timeb.h :
.Bd -literal -offset indent
/*
* Structure returned by ftime system call
*/
struct timeb
{
time_t time;
unsigned short millitm;
short timezone;
short dstflag;
};
.Ed
.Pp
The structure contains the time since the epoch in seconds,
up to 1000 milliseconds of more-precise interval,
The kernel no longer maintains the timezone and dstflag info, so 0 is
always returned for these fields.
