An alternative is ntpdate. That'll set your clock according to a server, rather than you doing so against your wristwatch. You use it with the name of a NTP server (see the man file for it).
e.g. ntpdate pool.ntp.org
NB: It doesn't want to work while you've got an NTP server running on the same box. If you have, service ntpd stop, would stop it. You could then restart it, afterwards.
You can use the -u option to ntpdate and it will work while the ntp daemon is running.
