Atomic TimeSync will set your clock using the best timekeeping source, the National Institute of Standards and Technology Once AnalogX Atomic TimeSync is set up, you can have it periodically set your system clock; plus it even has a built-in NTP server so you can synchronize all of your other computers quickly and easily! You can even specify a custom time offset to ensure that it sets your clock just the way you like it (I like my clocks 10 minutes fast, so I'm always a bit early). AnalogX Atomic TimeSync will set your clock using the best timekeeping profile, the National Institute of Standards and Technology.
