Time Tracking date format

[Hörður hreinsson]

I've set up my JIRA to show dates in a proper format. It still shows the date time like this 21/Sep/15 11:02 AM in the Date Started field, that also has a date picker. It should use the format that I have set up in Look And Fill in the configuration. ISO 8601 - Time and date format would be fine. How can I achieve this?

Look and Feel settings only affects how date and time is displayed. If you want to change format in the picker you have to change following property values from advance settings (System->General Configuration->Advanced Settings)

jira.date.time.picker.java.format=yyyy-MM-dd HH:mm

jira.date.time.picker.javascript.format=%Y-%m-%d %H:%M

jira.date.picker.java.format=yyyy-MM-dd

jira.date.picker.javascript.format=%Y-%m-%d
