Chronograph

Chronograph Atomic Time Clock is a simple award-winning program which keeps your computer's clock accurate using atomic time servers of the National Institute of Standards and Technology (NIST). You can work in Manual, Periodical, or Wait-for-Connection operating modes. Built-in dial-up networking, HTTP and SOCKS proxy support are included. The program is very stable; it automatically connects to another time server when the current server is down. Chronograph is able to replace the standard Windows clock in the system tray. It uses Winamp skins to display the digits, so there are thousands of different clock styles available to you!!!
