>> WRT years up to 9999 -- yes. The method I used consumes an extra byte after 2106... and then another in 4147. However, just one more byte buys up to 36812!

If we use seconds since epoch, set a new epoch, use a variable length
integer encoding for seconds since epoch, we get to 32 bits for a few
decades.  Four bytes.

If we use Julian days, set a new epoch, use a variable length integer
encoding for julian day then we can get down to 13-14 bits to start.
Add 12 bits for seconds, or multiply days by 3600 and add seconds and
we're under 32 bits -- almost as low as 24, but still 4 bytes.  Can't
get much better.
