[JUNGFRAU][CORRECT] Enable overwriting creation time
This MR is based on this ticket https://redmine.xfel.eu/issues/151141#change-553267 and the need to point the notebook to a different creation time to get different constants.
I separated the needed changes from !775 (merged) to a separate MR to be able to use it if the calcat_interface MR was delayed further.
Description
This can be used to skip using the raw data creation date and instead use a custom creation_time.
How Has This Been Tested?
Running relevant NB cells interactively.
Relevant Documents (optional)
Types of changes
- New feature (non-breaking change which adds functionality)
