This program will connect to one of the atomic clock 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.

It very easy to use: 1) Simply download and install the program. 2) Connect to the Internet. 3) Open Atomclock and press the Query button to compare your time to the Atomic Clock.
