How to set standard date and time format?

[David Stepanyan]

I have set the right format in look and feel but can't see that format in my project.

It's still in AM?PM format.

You can change the SQL display format under the SLA configuration. For more details on how you can update it, have a look at the following links:

• https://support.atlassian.com/jira-service-management-cloud/docs/set-up-sla-format-display/
• https://community.atlassian.com/t5/Jira-Service-Management-articles/A-fresh-look-at-SLAs-in-Jira-Service-Management/ba-p/1881636

Currently, it is not possible to modify the SLA data format through the look and feel settings. However, you can vote on an open feature request in the Atlassian public issue tracker and add yourself as a watcher to receive notifications moving forward.

There's no option to convert am/pm format to the standard form.

[Ivan Lima]

Okay. Now you're referring to the date that appears on your form. In this case, you need to configure the advanced settings. https://support.atlassian.com/jira-cloud-administration/docs/configure-advanced-settings/

You need to change the parameter jira.date.time.picker.javascript.format, which updates the date format on the client side. You can try something like %Y-%m-%d %H:%M.

Thank you for your reply. But I get errors.

Hey David, this is the jira.date.time.picker, which is indeed not supported in the new issue view. I mentioned the jira.date.time.picker.javascript.format, which changes the date format in the JSM forms, matching your screenshot.

[David Stepanyan]

The same problem exists.

[David Stepanyan]

I want the 24-hour format also in kanban fields.

[David Stepanyan]

Is it possible to change to a 24-hour format everywhere in Jira?

[Ivan Lima]

You would need to make changes in multiple places, which is confusing. Many discussions have been around this, and other users have reported difficulty making similar configurations. So you're not the first one to point that out.

For example, the new issue view is based on your language preferences. You can look at the available formats at https://support.atlassian.com/jira-software-cloud/docs/how-do-date-and-time-formats-work-in-the-issue-view/. 

The overall display for date/time can be changed at https://support.atlassian.com/jira-cloud-administration/docs/configure-the-look-and-feel-of-jira-applications/#Change-date-and-time-formats

For date/time pickers formats, you need to go to https://support.atlassian.com/jira-cloud-administration/docs/configure-advanced-settings/.

Also, you need to use data and time patterns from https://docs.oracle.com/javase/8/docs/api/java/text/SimpleDateFormat.html.

I'll leave another reference to a feature request in the Atlassian public issue tracker to address precisely this. Again, you can vote on and add yourself as a watcher to receive notifications going forward.
