Time picker in new issue view only shows hours from 9:00am to 6:00pm

Summary

In the New Issue view, when one wants to adjust the Start date and time, the only time interval available is between 9am and 6pm

Environment

• Jira Software Cloud
• New Issue View

Steps to Reproduce

1. In the Sprint view screen of a Scrum Project, click one of the issues and notice the New Issue view (pop-up screen).
2. Attempt to log time by clicking the + sign next to Time Tracking.
   This should only work if the issue already has some time logged.
3. Attempt to edit the Date started by clicking the calendar sign next to it
   Notice the time picker only shows the 9am - 6pm time interval

1. Expected Results
   The time picker should show a whole day time interval

Actual Results

The time picker only shows 9am - 6pm, in 30 minutes increments

Workaround

There are currently 2 workarounds:

1. Disable New Jira issue view under Profile → Labs section. This will bring the old issue view with another date/time picker
2. Edit the Date started field in Issue Detail View.
   1. Click on the issue key on top of the New Issue view
   2. Log work on Issue Detail View
