[Glass] Should "DateAndTime now - DateTime now" give something closer to 0 seconds than -36524:15:59:59.027

[PAUL DEBRUICKER via Glass]

DateAndTime now - DateTime now

I know they're not polymorphic out of hte box, but it seems like an error or the correct duration would be better than what happens now.   

I checked it on 3.3.0 and 3.2.4.  


Reversing the calculation e.g.

DateTime now - DateAndTime now

gives dnu error for #- in DateTime.
