Atomic Clock Sync can help you optimize how often Windows references an atomic clock server, such as the atomic clock servers operated by the National Institute of Standards and Technology (NIST) in the United States. Your current computer time is compared with the current atomic time and an adjustment is made to keep your local computer up-to-date with the exact time now. Atomic Clock Sync can even help repair the Windows Time Service if your computer is no longer able to check for Internet Time updates as it normally would.
