That's what I meant in previous post. Ntp can give me the reference to
estimate the drift of RTC, but this estimate can be calculated during
system up period. During system down drift can be totally different
(i.e. because the weather changed). So by applying some corrections we
can make more harm than good.

What link did I delete?

DS3231 eats 1000x more power than my current RTC.
