      How do I convince a DS3231 to output seconds since 1/1/2000? I can’t find anything in the DS3231 data sheet describing such a function.

        If you’re using the DS3231 library, you can use the following code:

        DateTime now = RTC.now(); //get the current date-time
        currentepochtime = (now.get()); //seconds since 1/1/2000

        Look at the “now” example that comes with the DS3231 library to see the whole sketch.
