ENH: Show unit information in repr for datetime64("NaT") #29396
Conversation
Unlike timedelta objects, datetime64 does not display its unit in the repr output (see numpy#28496). To maintain backward compatibility, this change adds unit information only when the datetime64 object has a NaT value.

I guess technically we could define a new numpy 2.3 legacy print mode as well. I don't know if it's worth the ceremony just for this.

Thank you for the comment! Defining a new print mode feels like a bit too much as well, but I'm happy to give it a try if needed.

Add a new release note for the change that shows time unit in the __repr__
output of datetime64("NaT"). See numpygh-29396.

Let's bring it in. If anyone reads this in the future because of downstream test failures please open an issue and we can reconsider adding a new legacy print mode. |
