Windows XP Clock Time

I have Windows XP Home Edition, SP2, and IE6, SP2.

When I go to the time in my task bar and I choose Internet Time, Server time.nst.gov and update, I get “An error occurred while Windows was synchronizing with time.nst.gov. If I choose time.windows.com, I get: An error occurred while Windows was synchronizing with time.windows.com

I have Zone Alarm as a firewall and I went to the Control Panel and selected Windows Firewall, but I still get the same error messages. How can I get the update to work? Thank you.

 

I have used other time names to get updated times.
