Problem

1. In Cockpit, go to batch operations page
2. Select the "Set Removal Time For Historic Process/Decision Instances / Batches"
3. Select the "absolute" mode
4. An input field is shown to select an absolute removal time

=> It might be difficult for some users to adjust the date represented as a string

Solution
Introduce a date picker to easily select the removal time

=> This might lead to an improved UX

Considerations

• Might break consistency in Cockpit since there is no place where we use datepickers so far (we only use datepickers in Tasklist)
  • Right now, whenever it is possible to submit a date in Cockpit, a date string must be passed (e. g. see job suspension to a later point)
