The existing date/timestamp code has no chance of dealing with that,
I'm afraid --- I doubt the code is likely to work for negative Julian
dates. Its underlying assumptions are pretty much fantasy anyway,
that far back. Nobody was using the Gregorian calendar then ...
Do you really need microsecond, or even day, resolution in your dates?
I wonder if it'd not be good enough to store the year as an integer.
