Incorrect date (d‏/M‏/y GGGGG h:mm a)

hello ,
i am try to add date in arabic format but i got ‘Incorrect date (d‏/M‏/y GGGGG h:mm a)’
here the date input based to the date/time picker ‘١٥‏/١٢‏/٢٠٢٤ م ١٢:٠٠ ص’ …
Now how should fix the date format based to that input ?
i have try to change it from locale settings ‘time : hh:mm a , date:dd‏/MM‏/yy’ but still get same error .
thanx.

The default PHP Internationalization extension locale for “ar-SA” is “d‏/M‏/y GGGGG”, note that there is a Unicode Character (U+200F) after “d” and “M”. If your keyword does not enter such unicode characters, you may click Tools → Locale Settings to enter your own format.

Thanx editing the locale “ar-SA” instead of “ar” solve my problem .
