.SH NAME
gettime \- get or set system date and time
.SH SYNOPSIS
.B gettime
[
.B -s
] [
.I timehost
]
.SH DESCRIPTION
.I Gettime
obtains the date and time from a specified host using the UDP \fItime\fR
protocol described in Internet Request For Comment (RFC) 868, and
writes it to the standard output
in
.IR ctime (3)
format.
If \fItimehost\fR is not specified, a compiled-in default (currently
dcn1.ARPA) will be tried.
If the optional
.B-s
flag is supplied, and if the program is being
run by the super user, \fIgettime\fR will set the date and time on
the local host using the
.IR settimeofday (2)
system call.
.PP
.I Gettime
is normally executed at system startup from \fI/etc/rc\fR to set the date and
time on the local host from an authoritative source.
