Yes I was referring to clock time.

Basically, if I were to set up shop in the middle of nowhere (e.g Australian outback), what would I need in addition to one of your fancy cesium frequency standards ?

i.e. on the basis of zero external input (no phones, faxes, internet) .... how do I decide what the clock time is ?

I know the old story of the sundials, but that seems too inaccurate... are you really saying watching the stars is more accurate ?
