I finally discovered the easiest way to use your local time server pool to get the correct time on Suse 10.2. This procedure will probably work with other Suse's, and even with other distros. I discovered it while setting up my BT HomeHub, which is a Thomson SpeedTouch in a silly box, but it does have a VoIP phone socket, and an 802.11b/g AP.
In YaST select Network Services
> NTP Configuration
Under Automatically Start NTP Daemon

Unselect Configure NTP Daemon via DHCP
Select Open port in Firewall
The click Advance

which doesn't exist.
I now have to find out how to do this on FC6 with Gnome.
