This freeware Atomic Clock Sync utility can help you keep your local computer
up-to-date with the exact current time. This program will reference an atomic
clock server to get the current time with the greatest accuracy available and
update your PC's information. It can even be set to automatically check the
time once a day to keep your PC's time accurate forever.
This program DOES NOT CONTAIN ANY SPYWARE or ADWARE! We provide it free simply
to promote our World Time Server web site!
Atomic Clock Sync will connect to one of the time servers operated by the National
Institute of Standards and Technology (NIST) in the United States, and will
compare the time of your computer with the time on the servers operated by the
NIST. This program will then display the difference between your system and
the servers and if greater than 15 seconds, it will offer you the option of
adjusting your PC by the displayed amount.
The overall uncertainty in this comparison should be no worse than +/- 5 seconds
under all circumstances and will be substantially less than this value in most
cases.
Version 2.5 adds the ability to have Atomic Clock Sync start automatically when
Windows boots up and to have it start minimized to the system tray. Some users
of previous versions were having trouble connecting to a functioning time server
and were getting an error regarding 'not an integer' which has been corrected
in the current versions.
Version 2.7.0.3 allows the program to start minimized, fixing a problem with
earlier releases of 2.7.
