[5.3] FIX mistyped dates

[tkuschel]

Pull Request for Issue #45369 .

Summary of Changes

1. In javascript, if the year size is entered greater than 9999, the current year is used.
2. When entered a two-digit year number (already implemented): if the year is greater than 39, then 1900 is used for the decade, otherwise 2000. (November 2016 it was the year 29). Now use a constant TWODIGITYEAR.
3. In the CalendarField, if the format() when using filterFormat fails, a meaningful error message is generated (Hardening).

Testing Instructions

Proper date: 2025-04-23 12:01:40
Mistyped date: 20225-04-23 12:01:40

Almost but not quite

Data Entry

After Save

[brianteeman]

For the farsi changes it needs to be tested by a native speaker but as far as I can tell it does not work as described in the PR. Instead of a fatal error you get an invalid date message - which is better than it is now but not as described

[tkuschel]

@brianteeman : After checkout, did you make a
npm ci
in your test environment?
The invalid data message only appears if the javascript is not build into compressed form.

[brianteeman]

yes of course

@brianteeman Can you tell me your test environment:

1. Used Web browser,
2. Server nginx, ...
3. OS
4. Which kind of message do you get / output?
   So I can look at it again.

[brianteeman]

did you test using arabic or were you pasting an english character date? From looking at your code you are assuming that the year is in the gregorian calendar. ie 1900 or 2000. ~The current year in the jalali calendar is 1404

[tkuschel]

I did not translate the date in the error message to jalaali. I know the year 1404. I'll look at the Farsi language, please be patient, as RTL is a little unfamiliar to me.

[brianteeman]

My gut feeling is that this PR is taking the wrong approach. I would just be outputting an error message stating that the input is incorrect and NOT trying to correct it.

[tkuschel]

Work in progress, do not test code. Should I close the PR and reopen when I am done?

[brianteeman]

You can close it or change it to a draft
