My new macbook pro knows time correctly at home ( using one of the nist servers ).

At work I have a different location setup and proxies configured ( http and https and ftp I think ) and everything seems to work. I can check for updates, use safari, connect to app store and iTunes etc. But the time is off ... and cannot seem to sync.

There are several other protocols I guess I can configure a proxy for. Does anyone know which of them the time sync uses?

Thanks John

UDP on port number 123, but you can change the time server apple uses in the Date & time preferences.

Using the http proxy should work fine.
Check your system log for errors as well.

Well the http proxy was already configured and it was not synching.

I went ahead and configured all the available remaining proxy's listed ( SOCKS, Streaming, Gopher ) ... and now it is working.

Prior to that change I just had http, https, and ftp proxy info set.

It would be nice if you just configured one of them ( http ) and then clicked and said that all the rest of them use that same information.

But anyway it is working now ... thanks.
