[time-nuts] What do people use for measuring temperature?

[John Moran, Scawby Design]

Would not a band-gap temperature sensor such as the LT6657 be better than a thermistor for precision, low drift applications?

The above device has 30 ppm/√kHr long-term drift. That should hold a mk for a fair few years.
