Dimension 4

Dimension 4 is the fastest and easiest solution to synchronize your PCs clock for Windows-based operating systems.
Dimension 4 uses one of a few well known and broadly implemented internet protocols to connect with publicly available time servers that have been operating on the Internet for over 15 years. These time servers typically have their very own atomic clocks, or are directly connected to other machines that do.
At an interval you specify, Dimension 4 connects to a time server that you choose from an exhaustive list of time servers. The time server then sends the correct time back to your computer, where Dimension 4 uses sophisticated algorithms to correctly adjust your PCs clock to with-in a few milliseconds of the real time.
