Years ago I was involved in some work on clocks that needed very high performance at low cost. We ended up with OCXOs GPS-disciplined over some of their frequency and atomic clock disciplined (cesium, IIRC) over another part of the range.

Telling the time is hard.

Cool. I bought a couple of HP Z3801A recently for home lab use. Also have an Arbiter GPS disciplined clock at work as a frequency standard for my RF equipment; they use one of the Wenzel OCXOs that has the lowest phase noise you can buy.
