I'm a little hesitant to do that as well.  My binary arithmetic is 
pretty ordinary at the best of times, and I do often find myself 
checking dates in planets to figure out various problems.  Another 
problem is that it will require synchronously updating a lot of tools to 
use the new format.

If we had a binary planet format then unix time might be appropriate.
