Return a Practically Guaranteed Unique ID in ASP

This ASP function does not return a globally unique ID, but it does return a random 10 digit string followed by a time string that is precise to the second. For most practical purposes, it will suffice as a unique identifier. If you need to return a true globally unique identifier, you need to encapsulate a call to the CoCreateGUID API function (see http://www.freevbcode.com/ShowCode.Asp?ID=21) into a .dll and call that .dll using Server.CreateObject.
