+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.

+sntpc [\fB\-bhnv\fP] [\fB\-p\fP \fIport\fP] [\fB\-s\fP \fIserver\fP] [\fB\-t\fP \fIthreshold\fP]
+.SH DESCRIPTION
+.sp
+\fBsntpc\fP queries an NTP server for the current time, and sets the
+local clock to the time reported by the server. It\(aqs a standalone
+binary, with no config file and no dependency on the \fIntp\fP package.
+.sp
+\fBsntpc\fP does not run as a daemon like \fBntpd\fP does. To keep
+the time in sync, you can run \fBsntpc\fP from root\(aqs \fBcrontab\fP(1)
+every 30 minutes (or however often it\(aqs necessary).
+.sp
+\fBsntpc\fP requires root access to actually set the local clock,
+although it can be run with \fB\-n\fP by non\-privileged users (e.g. with
+\fB\-v\fP to simply check the local time against the server\(aqs time).

+DESCRIPTION
+===========
+
+**sntpc** queries an NTP server for the current time, and sets the
+local clock to the time reported by the server. It's a standalone

+
+**sntpc** requires root access to actually set the local clock,
+although it can be run with **-n** by non-privileged users (e.g. with
+**-v** to simply check the local time against the server's time).
