CDAWeb "only digits are allowed in string" BAR_1B_L2_FSPC

This is an interesting error the verifier found:

wget -O - 'http://localhost:8280/HapiServer/hapi/data?id=BAR_1B_L2_FSPC&time.min=2013-01-08T00:02:24Z&time.max=2013-01-08T23:40:43Z'

I ran into a new error, where it would hang after an hour. This was because in the time-handling code for TT2000s (a long), I used "/" instead of floorDiv, so it would get stuck because it would round to 0, not -1. This is fixed, but I'm not sure this fixes the original bug. (Actually I think it does, because the bug was caused when the hours were negative, so you would get 2013-01-08T01:-1:00 for the time.
