Importing usr.sbin/rdate

Browse source 
Import the NetBSD rdate command and remove the Minix rdate command.
The default behaviour for both is the same. The NetBSD version adds
options to just display the time, adjust the time using adjtime(),
and set the time without printing the time.

Porting Notes:
 - Compiles cleanly out of the box without any warnings
 - Path changes from /usr/bin/rdate to /usr/sbin/rdate
 - checked pkgsrc for any usages of rdate (none found)
 - checked src for any usages of rdate (none found)

Testing:
 - all command line options work (tested with time.nist.gov server)
 - Native and cross build OK

.SH NAME
rdate \- set time and date from a remote host
.SH SYNOPSIS
.B rdate
.IR host " ..."
.SH DESCRIPTION
.B Rdate
obtains the current time from a remote time server. If run by the
super-user then local time is set to that time. The time of the remote host
is printed on standard output.
.PP
More than one host name may be specified. They are tried one by one until
one responds.
.SH "SEE ALSO"
.BR date (1),
.BR readclock (8),
.BR inet (8).

.Dt RDATE 8
.Os
.Sh NAME
.Nm rdate
.Nd set the system's date from a remote host
.Sh SYNOPSIS
.Nm
.Op Fl psa
.Ar host
.Sh DESCRIPTION
.Nm
displays and sets the local date and time from the
host name or address given as the argument. It uses the RFC 868
protocol which is usually implemented as a built-in service of
.Xr inetd 8 .
.Pp
Available options:
.Pp
.Bl -tag -width indent
.It Fl p
Do not set, just print the remote time
.It Fl s
Do not print the time.
.It Fl a
Use the
.Xr adjtime 2
call to gradually skew the local time to the
remote time rather than just hopping.
.El
.Sh FILES
.Bl -tag -width /var/log/wtmp -compact
.It Pa /var/log/wtmp
A record of date resets and time changes.
.El
.Sh SEE ALSO
.Xr adjtime 2 ,
.Xr gettimeofday 2 ,
.Xr utmp 5 ,
.Xr inetd 8
