JM and JMS date formats don't work

[Jumanjidev]

Can we access your project?

• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

The current behavior displays 24h format hour and apparently the issue is only on interface settings, but under custom code those formats work well.

Expected Behavior

The format should return 8:00 am.

Steps to Reproduce

1. Create new page
2. Drag a text widget to show data
3. Set supabase custom action or API Call to return datetime data
4. Select action output
5. Set jm format either from preset list or choosing custom and writing jm

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Hi! I'm sorry you're experiencing this issue.
What’s happening is that the jm format is locale-dependent.

• In English (en), jm is interpreted as h:mm a (12-hour format with AM/PM).
• However, in other languages like Spanish (es), French (fr), etc., the default convention is to use the 24-hour format. So jm returns something like 17:30 without AM/PM.

But no worries! Here’s a simple workaround:

Set the DateTime format to custom and use the following format:

h:mm a

If I understood correctly, this should return the format you're expecting.

Here’s a helpful link with more info: https://docs.flutterflow.io/resources/data-representation/global-properties/#current-time

I hope this helps!

Thanks, @Juansarmi. Very thoughtful of you. Just out of curiosity, is it possible to make jm not local-dependent? Cause this doesn't happen using code, so I still see it as an issue.

Hi again!
I'm glad to hear that this solved your issue.
You can also set the project language to English (or another language where this format is standard), and that should make "jm" display in the desired format.

Best regards!
