AtomTime98 connects to the atomic timeserver in Boulder, Colorado, and fetches the current atomic time. It compares this to your PC's time and displays the difference. You then have the option of updating your PC to match the atomic value. A number of options help you automate the update process. AtomTime98 also features support for most proxy servers.
Version 2.2 features an updated internal timeservers list and automatically remembers the last working timeserver.
