31.Sh NAME
32.Nm ftime
33.Nd get date and time
34.Sh LIBRARY
35.Lb libuitl
36.Sh SYNOPSIS
37.In sys/types.h
38.In sys/timeb.h
39.Ft int
40.Fn ftime "struct timeb *tp"
41.Sh DESCRIPTION
42.Bf -symbolic
43This interface is obsoleted by
44.Xr gettimeofday 2 .
45.Ef
46.Pp
47The
48.Fn ftime
49routine fills in a structure pointed to by its argument,
50as defined by
51.In sys/timeb.h :
52.Bd -literal -offset indent
53/*
54 * Structure returned by ftime system call
55 */
56struct timeb
57{
58	  time_t  time;
59	  unsigned short millitm;
60	  short   timezone;
61	  short   dstflag;
62};
63.Ed
64.Pp
65The structure contains the time since the epoch in seconds,
66up to 1000 milliseconds of more-precise interval,
67The kernel no longer maintains the timezone and dstflag info, so 0 is
68always returned for these fields.
