The VXWorks port I did (as a Cygnus contract to some part of NASA that had gotten hit with a "security mandate" used basically that trick, because we couldn't assume the hardware had any realtime clock at all, so we had to stash something and work with a tick counter.) Hmm, https://web.mit.edu/eichin/www/embedded-kerberos.html https://web.mit.edu/eichin/www/embedded-kerberos.html mostly talked about porting, and doesn't mention the clock problem - that was the right project though.
