Very good start. One minor thing; there is a extra "0" in your first example (should be 20100202).
We have been using that date format in the Geography & Map Division Scanning Lab for years in a table of administrative metadata because it sorted the well and was easy to see groupings. While good for machines to parse, it is also something humans can quickly learn to read. My only question is how will you deal with BC dates? We have not had to face that at our shop.
The time field is not something we have used, but it makes sense and if needed, is the most logical way to display this data. Those who are more familiar with "military" time will have less of a learning curve, but I don't foresee anyone being stumped by this. The "T" in front is great as a hint for what the data is all about, since time is rarely displayed as a number without some punctuation (i.e. 12:10).

I'll get the discussion started.
See the first proposal on the list at http://www.loc.gov/standards/datetime/proposals.html. (Just because it's the first does not mean that these have to be discussed in order. Anyone who wishes to initiate a thread on any of these proposals, please do. Please use a meaningful subject line, though.)
Please comment on whether the feature discussed below is useful. Would you use it? implement it? Please feel free to say no, it is not useful.
Abstract dates and times.
is February 2, 2010
would simply mean February 2. (As in "Groundhog Day is February 2".)
I am not suggesting this particular syntax, just using it as an example. I suggest we avoid the syntax discussion and focus on the functionality, and if it seems that this is a feature worth adopting then talk about syntax. Also, holidays with no fixed date, Easter for example, are out of scope for this thread, they are part of a different proposal.
Similarly for time.....
means 1335 (1:35 PM), April 12, 2009
would mean 1335 (As in "Sunday day game start times are 1:35 PM".)
(There is a third part to the proposal but let's put that on a separate thread.)
