Sure, that 621672192e5 value is 0000-01-01T00:00:00.000Z, so the "first day" of the Gregorian calendar, if we have two dates and we subtract that, we get the "difference" between those two dates ... this is still the "cheap/non-exact" version, if you want something more useful, you might have to update it so it does the actual values for each property. I might do that later so the example is more useful for other folks.
