This program is provided free of charge.  Please feel free to use it any way you wish or to redistribute it, provided you do not alter the program in any way.

This program connects to one of the time servers operated by the US National Institute of Standards and Technology (NIST), and will set the time of the clock in your computer with the atomic time-scale operated by NIST.

This program has an option to run in AUTOMATIC MODE.  When this option is selected, it will connect to the atomic clock 1 time per day and will not try to attempt another 24 hours.  If your system is not currently connected to the Internet, it will attempt to make a connection at regular intervals until a successful result is achieved, at which time it will not make any further attempts until the next day.

The overall certainty in the time comparison should be +/- 1 to 2 seconds.

For users behind firewalls, you may find it useful to know that Port 13 is used to connect to the NIST Atomic Clock servers. If this port is blocked, it may prevent Atomic Clock Sync from receiving time information.

For additional information, please consult the various help messages.
