Actually, I do have an earth available for calibration to my lab. It's just outside the window. During the day I can take sun sightings, and during the night star sightings (barring cloudy weather). I cannot measure the length of a second as accurately as other lab equipment can, but the expensive equipment in my lab that measures the second accurately cannot tell me time-of-day or day of year. (with the exception of a WWV or GPS receiver).

Yes, but you don't have it hanging in a neat position in your office, living room or lab, now do you? Besides, if you are a time-nut your rock will be more time-accurate than the real thing. :) I haven't special ordered a backup earth for my lab, or at least I won't admit to it, as you all know that I have at least three operational and a few stand-bys to put into operation in case I need to service one of them.
