Third time this year I've run into this … I can't believe in this day and age I have to either pull out a slide rule or go to AI to figure out the number of hours between 2 dates 😣, and pray that the humungous dropdown goes that far.
I just want to tell you when it closes.  DateTime.  So simple.

Agreed. Some requests are impossible to create the proper end date.

Example: Event on July 7 19:00, registration to close on July 26 00:00

Cannot use hours as it is more than 200 hours.

Cannot use days as it would not fall on correct time.

Ideally I should be able to close the event on the exact date/time July 26 00:10
