Hi Nathaniel, It differs by allowing time zone info to be preserved if supplied. A naive datetime64 would be unable to handle this, and would either have to ignore the tzinfo or would have to throw up an exception. The current suggestion is very similar to a naive datetime64 and only differs in being able to handle the given tzinfo, rather than ignoring it or telling the user that the current implementation cannot handle it.
This would be superioir to a naive dateime64 for use cases that have the tzinfo available, and would avoid the users having to workaround NumPy's inability to handle them if provided. A big thanks to Chris Barker for the write up linked in the proposal, it makes it very clear what the various possibilities are for improvement.
