Atomic time and auto-DST

Atomic timekeeping and automatic daylight saving adjustment reduce manual setup and keep timestamps consistent for logged temperature readings

Opt for clocks that support multiple sensors or sensor bundles if you plan to monitor several outdoor locations or split microclimates
