Always back up your data before performing any modifications to the database. If possible, test any alter, insert, update, or delete SQL commands on a staging server first.
Problem
At times when the administrators wish to edit the date/time format externally - not via Administration >> System >> Look and feel - they can do so by using REST API or direct modification to the database.
Resolution
REST API
Send a PUT request to /rest/api/2/application-properties/\{id\}. For example:
curl -k -D- -u username:password -X PUT --data '{"value" : "HH:mm"}' -H "Content-Type: application/json" <BaseURL>/rest/api/2/application-properties/jira.lf.date.time
This will modify the Time Format to HH:mm. The default value is h:mm a
Database query
The following query will return the current date/time formats.
select pe.entity_name, pe.property_key, ps.propertyvalue from propertyentry pe, propertystring ps where pe.id = ps.id and pe.property_key like '%.date.%'Edit the database accordingly and restart JIRA.
