    It’s not the overflow that’s the issue, but a calculation failure that causes the date value to be “0” and thus list the date as January 1, 1970. It’s happened to me several times with Pokemon GO.

      In this case, it is the overflow as 01111111...11111111+1 in binary becomes 10000000...00000000.

      But yes, some programs erroneously fall back to 0 in case of a null value, which corresponds to 1970-01-01. That’s why so many geotags were recorded for Null Island.
