Don Cross 503538da12 PY: Fixed calendar/time conversion functions for extreme year values.
Applying the same recent fixes to C and C# to the Python code.

I'm also changing my philosophy of representing times.
From now on, they will be truncated to the floor millisecond,
not rounded to the nearest millisecond. This means we don't reach
another calendar date until we have had 60 full seconds after
the last minute. Otherwise there is too much nasty logic for
rounding up calendar dates. I will follow suit across all languages.
