I suspect that Eric has not dived into TESTFRAME since he does not have a good mental model he likes yet. That is the hard part, and the part I think he is unsure on. If it were me, I'd consider shimming a few syscalls: adjtime(), send(), recv(), clock_gettime(). Maybe at the runtime linker level, maybe at the libntpd_lib.a level. Then run a good ntpd in record mode. With that saved data, a test ntpd could be run in playback mode. To keep the playback time small, maybe also a way to save internal state to a file, and reload that state in a test ntpd. A nice state dump could also be a good debugging tool.
