Free atomic time servers software for windows

Atomic TimeSync - Syncronize time from NIST How do you set the time in your house? I dont mean do you know how to set the clock on your VCR, but what TIME do you actually enter? Do you just use the normal best guess approach that practically everyone else does? If so, then get ready for the real deal - set your clock using THE timekeeping source, the National Institute of Standards and Technology.
NIST keeps the primary frequency (time) standard for the United States, and operates a special server using the Network Time Protocol (NTP) to allow Internet users to get the time from them! Of course, if youre not based in the US, dont worry, you can go to the NTP Homepage and get a listing of servers worldwide, so you can pick the one closest to you.
Once ATS is set up, you can have it periodically set your system clock; plus it even has a built-in NTP server so you can synchronize all of your other computers quickly and easily! You can even specify a custom time offset to ensure that it sets your clock just the way you like it (I like my clocks 10 minutes fast, so Im always a bit early).

Synchronize your clock with atomic clock. Atomic Time Synchronization application was designed to help users synchronize Local System Clock with Atomic Clocks around the USA.
You choose your server, select your regional GMT decal and then you can easily do synchronization
System requirements:
- Pentium I 166MHz
- 32Mb RAM

The first accurate atomic clock was made in 1955. This led to the internationally agreed definition of the second being based on atomic time.
Under the International System of Units, the second is currently defined as the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium atom.
Feel the rhythm of the Universes symphony with the Atomic Clock screensaver and always know the accurate time!

Atomic Clock NTP Time Client allows a client to synchronise time to a selected NTP server TimeTools SNTP Client Software is a freeware program that runs on any Windows workstation and server. This software will allow a certain client to synchronise time to a selected NTP server.
The utility periodically polls the specified ntp server at periodic intervals specified by the user and optionally synchronises time to the server.
TimeTools SNTP client software and the Windows Time Synchronisation service (Windows Time) cannot co-exist on the same system, since they both attemp 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 server monitor to synchronise time.
Main features:
- Operates with unicast or broadcast NTP or SNTP
- Full audit log
- Ensures system time of client closely tracks that of an NTP server.
- Windows 32 bit service.
