Improve time entry format on new issue view's date time picker custom field

Summary

Date and time picker field currently does not accept custom AM and PM times and has to be input in a specific format to display correctly.

Environment

Jira Software Cloud
New Issue View

Steps to Reproduce

In new issue view, results of inputs in a custom date time picker fields are:

• 9:42 AM -> Blank input
• 09:42 AM -> Works as expected
• 9:42 PM -> Blank input
• 09:42 PM -> Changes to 9:42 AM
• 21:42 -> 9:42 PM

Outside of this, customers do have the option use a dropdown menu to select time in AM and PM in 30 minute increments.

Expected Results

Customers should be able to input time in 12 hour formats into the date time picker without having to make any edits like the ones in the previous section.

Actual Results

Inputs blanking out based on the format they are added in.

Workaround

Currently the only workaround is shown in the steps to reproduce section,
i.e. by inputting time in specific formats as displayed.
