Summary

JIRA Software/JIRA Agile does not use the ISO8601 formatting for its date pickers.

Environment

JIRA with JIRA Agile/Software.

Steps to Reproduce

1. Setup a JIRA instance with Agile/Software installed;
2. Navigate to Administration > System > Look and Feel and set JIRA to use ISO8601 formatting for date pickers;
   1. "Turning it on will cause Monday to be the first day of week in the Date Picker, as specified by the ISO8601 standard"
3. Navigate to an existing or create a new Agile Scrum board;
4. Create a version using the sidebar under Backlog view;
5. Observe that the date pickers will not respect the ISO8601 setting from JIRA;

Expected Results

JIRA Software should consistently use the ISO8601 setting if it has been configured in JIRA.

Actual Results

JIRA Agile does not apply this setting, as a result the date pickers behave in an inconsistent manner.

Notes

The original report included the following information:

This can be seen in two different places:
Administration -> Greenhopper Configuration -> Non Working Days.
Configure Board -> Non Working Days -> Add Date Button

Workaround

No known workaround.
