An external portion or burb of a host computer receives messages from external servers representative of accurate time from one or more peer computers coupled by a network. A process called a client on the external burb processes the messages and then accurately sets a host computer clock. Processes called servers running on an internal burb which may not communicate directly with peers, then access the clock to obtain a correct indication of network time without having to communicate directly with the peer computers. The time is then provided to internal clients. This allows a host computer without an expensive clock to update its clock and enable it to provide accurate time to processes running on the host.

[ What is claimed is:] [1.] A method of determining time in a host coupled to a network having one or more accurate time keepers comprising the steps of:requesting time from an external server via an entity operating in an external portion of a firewall system;receiving a communication in the external portion of the firewall system from the external server containing an indication of time; andadjusting a clock register based upon the indication of time received from the external server wherein the clock register may be read by entities operating in an internal portion of the firewall system which entities may not directly communicate with the entity operating in the external portion of the firewall system.
