The clock is supposedly being synchronized with an Apple timeserver acording to date and time in System Preferences. However, it is at least 30 seconds off from my two linux machines which are being set once an hour with the nist.gov servers. This is really bothering me because I have chimes and announcements set to go off at different times and the other computers are done or almost done by the time my Mac starts. I'm sure the linux machines are more accurate because they are also in sync with my atomic clock. Is there something I can do to manually set this clock to the right time, even if I have to keep doing it periodically?Whatever is being done automatically doesn't seem to be working.

My date and time control panel allows you to choose another network time server. Nut then that's in OS 9.

The network time transport protocol does some testing to determine transit time to your machine from the network site. The closer the site is to you and the smallest number of routers in between the better off you are. But 30 seconds seems like a whole lot.

Macs offer an option to "check time whenever I need to".  It beats me how they determine when they need to without checking but they just might allow 30 or more seconds of local clock drift.
