I don't need an accurate time reference this is more for keeping an eye on how the project is running if I was to do this in a timer where I want something to happen on time.Something like the DS3231M on a battery would be nice, though. For example, the Pico RTC DS3231. Of course, then you have to decide on a strategy. Continue to use the built-in RTC and just set it at reset time? Sync once an hour? Only use the external clock? (That last one might not be practical if, say, you're timestamping a lot of records.)
The internal RTC is good enough for my purposes, if I went to external I would get one with some scratch RAM so I could keep data over prolonged power outage but then I'm looking at adding an FRAM to my project so not really required.
