Java Date / Date Time picker setting the wrong year value in a Date / Datetime field

Issue Summary

This is reproducible on Data Center: (yes)

When setting the java date /date.time pickers (Jira Administration>General configuration>Advanced settings) to show year as yyyy, customfields of the type date / timedate picker are setting the year as 0024 even when using the Date Picker

Steps to Reproduce

1. Add a Date / TimeDate Picker field to Jira and make sure to add it to some screens
2. Navigate to Jira Administration>General configuration>Advanced settings, and set the java date picker / date time picker to format the year as yyyy
3. Optionally, set year to yyyy in Jira's Look and Feel - this has no effect.
4. Create an issue, and select a Date using the Date Picker!image-2024-04-24-17-39-25-008.png|width=303,height=157!

1. Click 'confirm' in the picker (even if Look and feel is set for yyyy you will see
   
2. Proceed to create the issue - see the date is noted on the issue (if Look and Feel is set to yyyy you will see the year already as 0024):
   
3. If the Look and feel is still set to yy, one will only see this issue if trying to update the field inline:
   

Expected Results

Date is set per the Date / DateTime picker, with the correct year - 2024

Actual Results

The year shows, and saved into the DB is 0024, may not show on the issue view (if Look and feel is set to dd/MMM/yy), but will later fail in JQL search, as it falls way in the past

Workaround

Do not use the date picker, but manually type the full date /time and indicate the year in 4 digits
