Hi,
I have an issue with displaying date and time in user locale.
Prerequisites:
Jira Cloud Service Desk with Date Time field (in my case it's new custom field) for user input while creating an issue (for ex. incident).
Steps to reproduce:
- Log in as Service Desk user
- Go to your profile->'Edit preferences'-> and choose for ex. 'Norsk (Norge)'-> Save
- Make sure that language in the system changed
- Try to create any case in Service Desk which has Date Time field, select any value from Date and Time component:

- You'll get an error:

Although you can't do write the date (and time) in any other format
