ENH: bring back is_datetime_or_timedelta

[arden13]

Feature Type

• Adding new functionality to pandas

• Changing existing functionality in pandas

• Removing existing functionality in pandas

Problem Description

There was a feature present through pandas 2.0.x which allowed easy checking for datetime or timedelta. This was silently removed in 2.1.x breaking code we had currently working.

This is the previous function

Feature Description

See note above for function defined and ready to use

Alternative Solutions

At bare minimum please include this as an update to the documentation and provide a workaround. Silently breaking functionality for the purpose of speed enhancements is frustrating to troubleshoot.

Additional Context

No response

Sorry for breakage but as noted in https://pandas.pydata.org/docs/reference/index.html, any functionality, unless noted, in pandas.core is not guaranteed to be stable.

You could probably compose this functionality with public type checking functions in https://pandas.pydata.org/docs/reference/arrays.html#utilities

Well, thank you for the notification. I'll close the issue and find a workaround.
