Using Python as an example (and sticking strictly to what's in the standard lib): from uuid import uuid1 u = uuid1() print datetime.datetime.fromtimestamp((u.time - 0x01b21dd213814000L)*100/1e9) The constant `0x01b21dd213814000` represents the number of 100-ns units between the epoch that UUIDs use (1582-10-15 00:00:00), and the standard unix epoch.
