There's an ISO standard for today as 2001.10.24 (or maybe 2001-10-24).
Dates stored like this go back further than any genealogist is likely
to need (well, unless you can trace back to Adam). Moreover, they
collate, in that an alphabetic comparison between two dates reveals
which is later.
This solution of course does not address date ranges, or approximate
dates.
