Issue Summary

While performing a schedule override on JSM Operations, the time format always shows in 12hour format irrespective of user profile language selection.

This is reproducible on Data Center: (no)

Steps to Reproduce

1. Change the language to English(US) by navigating to your profile and we see the all-the-time format across the instance is changed to 12 hours.
2. Navigate to your profile again and change the language to English(UK). You will notice that everything has been changed to a 24-hour format, except for the schedule override.

Expected Results

• The time format on the schedule override should display the time based on the language preference as per this doc:- https://support.atlassian.com/jira-software-cloud/docs/how-do-date-and-time-formats-work-in-the-issue-view/ 

Actual Results

• The time format is always shown in 12hours

Workaround

Currently, there isn't any workaround. However, to have uniformity across views, having the language preference as English(US), the time will display in 12hour format.
