Why not? If the programmer is using strict tzinfos how would they end up with an invalid t? I only see two ways: - constructing from a literal (in which case an exception should be raised) - t is using a non-strict or missing tzinfo, possibly from an addition or subtraction (in which case we can't know which direction they were going and should not guess -- so raise an exception) -- ~Ethan~
