Hi,

My work on the PEP 410 tries to unify the code to manipulate timestamps. The problem is that I'm unable to decide how to round these numbers. Functions using a resolution of 1 second (e.g. time.mktime) expects rounding towards zero (ROUNDHALFDOWN), as does int(float). Example:

FWIW, that's ROUND_DOWN. ROUND_HALF_DOWN rounds up from > x.5.
