From the project
The core concept isn't anything "new" or "innovative" (see below) but the specific implementation is. While the implementation was specific to my needs, I'm publishing it because it may be useful for others as well.

My preferred router/firewall OS has a built in NTP server known as ntpd. Precisely how NTP works is beyond the scope of the document, but in short:
