If you are really worried about loosing track of true UTC time then buy a GPS receiver or if you are very concerned by three of them from three different manufacturers Having multiple GPSes that do not share common parts is nearly fool proof. These would serve a reference clocks for three NTP servers. Doing this is not quite as "nuts" as it sounds. I bet you could set up all three for under $1K if you used existing computers
Using Garmin 18 and SURE for two of those will leave you nearly $900 for the last clock, so that is obviously doable. :-)
If you pick up a Motorola Oncore UT+ as the last clock you'll have a proven extremely good reference (15-25 ns RMS offset from true UTC?) and still end up with maybe $800 in your pocket.
