Atomic Clock Sync: a free configuration utility
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.
Windows can do it ...
Windows has a built-in "service" that allows your computer to reference 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.
... but it is hard to configure
While it is great to have this functionality in Windows, configuring this time
service is painful! If you want to sync more often than the default, you have to
be very comfortable editing the System Registry OR you can use our Atomic Clock
Sync program to do the work for you.
so use Atomic Clock Sync and go the easy route
Atomic Clock Sync offers an easy way to configure how often your computer will
check in with an atomic clock server to keep your local system clock adjusted
for accuracy. The default in Windows is to sync every 7 days, but you can easily
change this to be more often if you find your computer clock gets behind or
ahead too quickly.
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!
Atomic Clock Sync includes no spyware! No ad banners! No cost! No questions asked!
We give Atomic Clock Sync away for free simply to encourage you to use and return to World
Time Server.com for the current times around the world. We appreciate your
loyalty and we thank you for sharing our site with your friends, too! Atomic
Clock Sync helps keep your
local clock accurate and WorldTimeServer has the accurate clocks for everywhere else!
