Rewording the issue title and reopening based on the python-ideas thread. The rationale for making this change is that the current behaviour converts a stylistic problem in checking values against a sentinel via "bool(value)" instead of "value is not None" into a subtle data driven behavioural bug that only occurs exactly at midnight UTC.

If someone wants to write the patch to deprecate this behaviour in Python 3.5 (reporting a deprecation warning whenever midnight is interpreted as False, perhaps suggesting the use of "is" or "is not" instead), and then actually change the behaviour in 3.6, I don't believe we should actively oppose them from doing so.
