Just make sure you're using the proper TZ enviroment and rdate works fine
from any server.

Use ntpdate when you bring the line up. Or chrony (which apparently
works well over dial-up lines).

Don't use it, then!

NTP has many advantages, such as comparing against multiple servers, strata
definitions, and an alogrithm to predict the drift of the hardware clock.

The machine should be running Internet Time service i guess to respond
to your rdate query.

Isn't rdate supposed to broadcast to the entire network rather than to
some host specifically ..!! i have'nt used it in a long time ..

You should probably consider using ntpdate and setting up your own NTP
server. It is much simpler and easier to maintain.
