It did not occur to me until now that it actually is possible to edit the server field in the Date & Time preferences window and that it is thus possible to use any timeserver one would want to use -- not just those provided by Apple. Just select the existing text and type the address of the server you want to use.

Or you could follow this hint from oh, about 2001.
Manually specify desired timeserver
Searching for "timeserver" in the Hints only gave me a hint about Windows XP. The hint you refer to was unknown to me ...
Manually specify desired timeserver
This is a hint? I hope I can add validity by adding to it.

In Leopard, you can use spaces (instead of commas) between potential NTP servers:

You can use an internal ntp server while in the office...How do you go about setting this up? I would love to have one Mac serving time to all the others, and everything I have read about ntpd suggests that this should be easy enough to configure, but I have never managed to get it to work. Ah well...

Don't know about OS X, but
ntpd is dead simple to set up on Linux. Just find an old box, install a simple distribution on it and enjoy your local time server. We do that at my work and, while it doesn't save us a ton of bandwidth, any little bit helps.

Hey, I just realized they finally fixed the problem in Leopard! I can now sync all the computers in the office to one running Leopard. Hmm...this might deserve a hint of its own...

This will also stop your computer from "calling home" to apple.com every day, which might be welcome if you are privacy-conscious.
ntp pool
my /etc/ntp.conf looks like this to use the ntp pool... This works for people in the US
<blockquote> server 0.us.pool.ntp.org minpoll 12 maxpoll 17 server 1.us.pool.ntp.org minpoll 12 maxpoll 17 server 2.us.pool.ntp.org minpoll 12 maxpoll 17 server 3.us.pool.ntp.org minpoll 12 maxpoll 17 server 0.north-america.pool.ntp.org minpoll 12 maxpoll 17 server 1.north-america.pool.ntp.org minpoll 12 maxpoll 17 server 2.north-america.pool.ntp.org minpoll 12 maxpoll 17 server 127.127.1.0 minpoll 12 maxpoll 17 </blockquote> Then use this to get stats of what you are using: <blockquote> ntpq -p -n </blockquote> See http://www.pool.ntp.org/

or you edit /etc/ntp.conf...
Control the Network Time Server settings from the command line
From the command line you can use the One of the downsides of the GUI System Preferences tools is that in the case of updating the system time requires that you open the Date and Time system preferences pane to trigger an update. I manage several dozen OS X server boxes, and this issue causes my servers to drift out of sync, leading to all sorts of problems. But creating a script that uses the network time server functions of the systemsetup command, combined with crontab, to force resyncing on a regular basis. The available commands are: Viewing or Changing Network Time Server Usage To see if a network time server is being used: To enable or disable use of a network time server: To view the current network time server: To specify a network time server: While this is a rather ham-handed way of doing things, creating a script that turns the use of the network time server off and then back on again will force the system to synchronize its clock with your desired time server. Create a cron job that runs the script as root once a day, or once a week, and you should no longer have problems with drifting time. |
