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.
