PC Atomic Sync - Version 4.0 (*) It is an atomic clock synchronizer with some useful features (time offset, synchronize periods, etc.). The main idea of the program is to synchronize your PC's clock in the most reliable and resource-saving way. (*) The unique Time Offset feature of the program allows setting up your PC clock to gain or to lose for a specified interval. Many our users value this feature greatly. (*) Clock in your PC needs to be corrected only several times a month. And it is this fact that defines the way the program works: the program runs when Windows starts, checks whether synchronization has been done this day already, and stops immediately if so. Otherwise the program checks for Internet connection, then tries to synchronize your clock and ends its work if succeeded. So as you see mostly the program is idle and is not wasting resources of your PC. Synchronization is done automatically while you are receiving your e-mail or surfing the web and no actions are to be done by you.
