Ok, so no fixed epoch, and arithmetic on Dates operates in integral days. Sold.
It would be handy to have some predefined constants for some common epochs, like JD, MJD, JD, etc. Those don't necessarily need to be in core for 6.0.0, though. Maybe a separate Date::Epochs module? Examples: const $JD0 = Date.new(-4713, 11, 25) ; # or Date::Julian.new(-4712,1,1) ? const $MJD0 = $JD0 + 2_400_000; const $RD0 = Date.new(0,12,31); (Those are assuming a continuous numeric range for years, with 0 = 1 BCE, -1 = 2 BCE, etc. Haven't double-checked the spec, but IIRC that's how it's defined.)
