Summary

When changing configuration related to the calendars at JIRA Administration > System, some changes doesn't take place within JIRA Agile.

Environment

JIRA Cloud

Steps to Reproduce

Change calendar configuration format as per Customizing the Look and Feel, in the section Date/Time format:

1. Go to JIRA Administration > System > Look and Feel
2. Set Date/Time format to 24 hours yyyy-MM-dd HH:mm
3. Check the box at the bottom to make Monday first day of the week, as per How to set Monday as First Day of Week
4. Go to JIRA Administration > System > General Configuration > Advanced Settings and enter the format (sysadmin only):

• jira.date.time.picker.java.format: yyyy-MM-dd HH:mm
• jira.date.time.picker.javascript.format: %Y-%m-%d %H:%M

Expected Results

Calendars will be showing Monday as first day of the week, and time will be displayed in 24 hours format

Actual Results

Calendars within JIRA Agile are still showing Sunday as first day of the week and am/pm format (see screenshots). The way date is displayed will change, but time seems to have no effect. In JIRA all changes have taken place correctly.

Workaround

There's no workaround at the moment.
