Synchronize your PC time with an atomic clock via the Internet. This application is simplifying the task to the outmost and sits conveniently to access in the startbar tray.
12-Sync adjusts the time repeatedly, automatically, and silently exactly on the dot. It waits for an Internet connection, then adjusts your clock at atomic precision, without your interaction. It keeps a log file about all activities that you can limit to size or age. You will never have the wrong time again!
