+.I sntp

+.B \-q
+indicates that it should query a daemon save file being maintained by it.
+This needs no privilege and will change neither the save file nor the clock.
+.PP
+The default is that it should behave as a client, and the following options
+are then relevant:
+.TP
+.B \-r
+indicates that the system clock should be reset by
+.IR settimeofday .
+Naturally, this will work only if the user has enough privilege.
+.TP
+.B \-a
+indicates that the system clock should be reset by
+.IR adjtime .
+Naturally, this will work only if the user has enough privilege.
+.PP
+The default is to write the estimated correct local date and time (i.e. not
+UTC) to the standard output in a format like
+.BR "'1996 Oct 15 20:17:25.123 + 4.567 +/- 0.089 secs'" ,
+where the
+.B "'+ 4.567 +/- 0.089 secs'"
+indicates the estimated error in the time on the local system. In daemon mode,
+it will add drift information in a format like
+.BR "' + 1.3 +/- 0.1 ppm'" ,
+and display this at roughly
+.I separation
+intervals (see under the
+.B \-x
+option for details).
+.TP
+.BI \-l " lockfile"
+sets the name of the lock file to ensure that there is only
+one copy of
+.I sntp
+running at once. The default is installation-dependent, but will usually be
+.IR /etc/sntp.pid .
+.TP
+.BI \-e " minerr"
+sets the maximum ignorable variation between the clocks to
+.IR minerr .
+Acceptable values are from 0.001 to 1, and the default is 0.1 if a NTP host is
+is specified and 0.5 otherwise.
+.TP
+.BI \-E " maxerr"
+sets the maximum value of various delays that are deemed acceptable to
+.IR maxerr .
+Acceptable values are from 1 to 60, and the default is 5. It should sometimes
+be increased if there are problems with the network, NTP server or system
+clock, but take care.
+.TP
+.BI \-P " prompt"
+sets the maximum clock change that will be made automatically to
+.IR maxerr .
+Acceptable values are from 1 to 3600 or
+.IR no ,
+and the default is 30. If the program is being run interactively in ordinary
+client mode, and the system clock is to be changed, larger corrections will
+prompt the user for confirmation. Specifying
+.I no
+will disable this and the correction will be made regardless.
+.TP
+.BI \-c " count"
+sets the maximum number of NTP packets required to
+.IR count .
+Acceptable values are from 1 to 25 if a NTP host is specified and from 5 to 25
+otherwise, and the default is 5. If the maximum isn't enough, the system needs
+a better consistency algorithm than this program uses.
+.TP
+.BI \-d " delay"
+sets a rough limit on the total running time to
+.I delay
+seconds. Acceptable values are from 1 to 3600, and the default is 15 if a NTP
+host is specified and 300 otherwise.
+.TP
+.BI \-x " separation"
+causes the program to run as a daemon (i.e. forever), and to estimate and
+correct for the clock drift.
+.I separation
+sets the minimum time between calls to the server in minutes if a NTP host is
+specified, and between broadcast packets if not. Acceptable values are from 1
+to 1440 (a day), and the default (if
+.B \-x
+is specified but
+.I separation
+is omitted) is 300.
+.TP
+.BI \-f " savefile"
+may be used with the
+.B \-x
+option to store a record of previous packets, which speeds up recalculating
+the drift after
+.I sntp
+has to be restarted (e.g. because of network or server outages). In order to
+restart the data,
+.I sntp
+must be restarted reasonably soon after it died (within a few times the value of
+.IR separation ),
+with the same value of the
+.B \-c
+option, the same value of
+.IR separation ,
+in the same mode (i.e. broadcast or client), though the NTP servers need not
+be the same for client mode, and with compatible values of other settings.
+Note that the file will be created with the default ownerships and permissions,
+using standard C facilities. The default is installation-dependent, but will
+usually be
+.IR /etc/sntp.state .
+.TP
+.B -4
+force IPv4 DNS resolution.
+.TP
+.B -6
+force IPv6 DNS resolution.
+.PP
+.B address(es)
+are the DNS names or IP numbers of hosts to use for the challenge and response
+protocol; if no names are given, the program waits for broadcasts. Polling a
+server is vastly more reliable than listening to broadcasts. Note that a
+single component numeric address is not allowed, to avoid ambiguities. If
+more than one name is give, they will be used in a round-robin fashion.
+.PP
+Constraints:
+.IP
+.B minerr
+must be less than
+.B maxerr
+which must be less than
+.B delay
+(or, if a NTP host is not specified
+.BR delay / count "),"
+and
+.B count
+must be less than half of
+.BR delay .
+.IP
+In update mode,
+.B maxerr
+must be less than
+.BR prompt.
+.IP
+In daemon mode (i.e. when
+.B \-x
+is specified),
+.B minerr
+must be less than
+.B maxerr
+which must be less than
+.B separation
+(note that this is in minutes, not seconds, but the numeric value is compared).
+.PP
+Note that none of the above values are closely linked to the limits described
+in the NTP protocol (RFC 1305).
+.SH USAGE
+The simplest use of this program is as an unprivileged command to check the
+current time and error in the local clock. For example:
+.IP
+.B sntp ntpserver.somewhere
+.PP
+It can be run as a unprivileged background process to check on the clock drift
+as well as the current error; this will probably fail if the local clock is
+reset while it is running. For example:
+.IP
+.B sntp -x ntpserver.somewhere > output 2>\&1 \&
+.PP
+With suitable privilege, it can be run as a command or in a
+.I cron
+job to reset the local clock from a reliable server, like the
+.I ntpdate
+and
+.I rdate
+commands. For example:
+.IP
+.B sntp -a ntpserver.somewhere
+.PP
+It can also be run as a daemon to keep the local clock in step. For example:
+.IP
+.B sntp -a -x ntpserver.somewhere > output 2>\&1 \&
+.PP
+More information on how to use this utility is given in the
+.I README
+file in the distribution. In particular, this
+.I man
+page does not describe how to set it up as a server, which needs special care
+to avoid propagating misinformation.
+.SH RETURN VALUE
+When used as a client in non-daemon mode, the program returns a zero exit
+status for success, and a non-zero one otherwise. When used as a daemon
+(either client or server), it does not return except after a serious error.
+.SH BUGS
+The program implements the SNTP protocol, and does not provide all NTP
+facilities. In particular, it contains no checks against any form of spoofing.
+If this is a serious concern, some network security mechanism (like a firewall
+or even just
+.IR tcpwrappers )
+should be installed.
+.PP
+There are some errors, ambiguities and inconsistencies in the RFCs, and this
+code may not interwork with all other NTP implementations. Any unreasonable
+restrictions should be reported as bugs to whoever is responsible. It may
+be difficult to find out who that is.
+.PP
+The program will stop as soon as it feels that things have got out of control.
+In client daemon mode, it will usually fail during an extended period of
+network or server inaccessibility or excessively slow performance, or when the
+local clock is reset by another process. It will then need restarting
+manually. Experienced system administrators can write a shell script, a
+.I cron
+job or put it in
+.IR inittab ,
+to do this automatically.
+.PP
+The error cannot be estimated reliably with broadcast packets or for the drift
+in daemon mode (even with client-server packets), and the guess made by the
+program may be wrong (possibly even very wrong). If this is a problem, then
+setting the
+.B \-c
+option to a larger value may help. Or it may not.
