about this freeware tool

While WorldTimeServer.com can help you look up accurate times around the world, our visitors have expressed much interest in our help to keep your local computer clock accurate, too. Atomic Clock Synchronization is the best way to make this happen.

Our freeware Atomic Clock Sync utility 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.

Best of all, you can download and use this utility at no cost to you!

No spyware! No ad banners! No cost! No questions asked! So why do we do give Atomic Clock Sync away as freeware? Simply to encourage you to use and return to World Time Server.com for the current times around the world. This tool helps keep your local clock accurate and we have the accurate clocks for everywhere else!


IMPORTANT NOTE: You must have the correct time zone selected on your computer AND have the correct daylight saving time rules in place in your operating system in order to have the Internet Time synchronize process work properly. If the dates for Daylight Saving Time (DST) changed recently in your area, you must update your operating system with the new rules. Microsoft releases patches when necessary for newer versions of Windows, but with older versions, you may have to update the registry yourself or find a third-party tool to do it.
