> it wasn't an accident, it was designed so modulo arithmetic could reasonably be implemented for time() objects (which hasn't been demanded or implemented since the datetime module was created)

Ah, interesting.  I just wrote a program last month where I was baffled that time didn't support arithmetic, and had to dodge painfully through datetime instances to do the arithmetic.  I asked about it on IRC and someone said it was because arithmetic on times was ambiguous because of timezones, and I just accepted that rather than wonder why it hadn't been implemented.

Otherwise I'm pretty sympathetic to the RFE, but I'd really like time arithmetic to work, so I guess I'd have to be -1 in that case, wouldn't I?
