Always On Time is a Windows Internet utility that will connect to one of a dozen public atomic time servers and fetch the current atomic clock time value. If a difference in time is discovered between the atomic time server and your PC`s clock, you then are able to update and synchronize your PC`s clock with the current atomic clock time. Automatically synchronizes your PC each time Windows boots up.
