OS NP Atomic Sync synchronizes your PC clock using a Web access method. This technology makes it fool compatible with proxies and firewalls that can prevent NTP protocol synchronization. It 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. The unique Time Offset feature allows setting up your PC clock to gain or to lose for a specified interval. Some of our users value this feature greatly.
