I remember one colleague concerned with casting a Java 64-bit millisecond timestamp to double seconds when crossing languages (over to a somewhat TypeScript-like financial modeling DSL developed in the mid-late 1990s, where it's a bit clunky to deal with numbers in any format other than doubles). I added a comment apologizing to software archaeologists on 12 October 287,396 C.E., when the precision of double timestamps (with 1970-01-01T00:00:00 UTC epoch) drops to 2 milliseconds, and the reviewer was fine after that.
