The Windows Atomic Clock NTP Client Software is a freeware SNTP utility that runs on any Windows 95/98/NT/2000/XP/2003 workstation or server. It allows a client to synchronise time to a selected Atomic Clock synchronised NTP server.
The Windows NTP client utility periodically polls a specified time server at periodic intervals specified by the user and optionally synchronise's time to an atomic clock ntp server.
Windows Atomic Clock NTP Client Software and Windows Time Synchronisation Service.
TimeTools SNTP client software and the Windows Time Synchronisation service ('Windows Time') cannot co-exist on the same system, since they both attempt to use UDP port 123 (NTP). You can disable the Windows Time service from the service manager to avoid this problem and rely on the NTP time server monitor to synchronise time.
Operation with Windows XP SP2 Firewall
To operate any NTP or SNTP client on Windows XP SP2 or later, you must open the NTP port (Port 123) in the Windows XP firewall. From the Firewall Control Panel add UDP port 123 in the exceptions tab.

24 January 2007: Atomic Clock NTP Client - add protection to reject any received NTP time stamps that are outside of a 15 minute when compared to the host computers system time. This would protect the hosts system time from being updated by a 'rogue' server. The disadvantage is that if the host computers system time is out by more than 15 minutes, it will not be updated.
