When copying and pasting the datetime tool, or disconnecting its input, it loses its configuration. This can be really frustrating if it has an unusual formula, and can result in looking up the datatime functions again: https://help.alteryx.com/current/designer/datetime-functions and working out how to reconfigure the tool.
Steps to reproduce this issue:
1. Set up datetime tool

2. Delete Input Connector:

3. Reconnect and notice the formula is missing and it has been reset to a completely fresh DateTime Tool:

Proposed solution:
The Datetime tool should remember the previous configuration, and go back to this when the input is deleted or it is copy pasted. It will then be able to be reconnected.
Steps in proposed solution:
1. Setup Datetime tool

2. Delete input Connector (Note the DateTime Config and Annotation Remaining, but still being not editable)

3. Reconnect the tool for it to still be configured for the data
