[Numpy-discussion] Dates and times and Datetime64 (again)

[Sankarshan Mudkavi]

I agree with that interpretation of naive as well. I'll change the proposal to reflect that. So any modifier should raise an error then? (At the risk of breaking people's code.)

The only question is, should we consider accepting the modifier and disregard it with a warning, letting the user know that this is only for temporary compatibility purposes?


As of now, it's not clear to me which of those options is better.

Cheers,
Sankarshan
