	It's very valuable for applications that communicate with the outside
world, if for no other reason than because your logs will have accurate
timestamps. :)  But seriously folks, accurate time is important for
mail, and apache has a section in their documentation about the
importance of accurate time for a web server. 

	It's also extremely valuable for transaction based systems where more
than one client is accessing a given server or servers. There's more
information on the www page that was quoted previously, I suggest you
give it a read.
