lib: Fix some issues in timeutils
In particular, dates prior to Mar 1, 2000 are screwed up.
The easiest way to see this is to do:
>>> import time
>>> time.localtime(0)
(2000, 1, 1, 0, 0, 0, 5, 1)
>>> time.localtime(1)
(2000, 1, 2, 233, 197, 197, 6, 2)
With this patch, we instead get:
>>> import time
>>> time.localtime(1)
(2000, 1, 1, 0, 0, 1, 5, 1)
Doh - In C % is NOT a modulo operator, it's a remainder operator.
