Y2K38 is fixed in MariaDB and PHP 8.3, but that is not mentioned in PhpMyadmin about phpmyadmin HOT 2 OPEN

I found this in the MariaDB documentation:

the TIMESTAMP data type can hold values between '1970-01-01 00:00:01' (UTC) and '2038-01-19 03:14:07' (UTC) (MariaDB 11.3 and earlier, 32-bit platforms ) or '2106-02-07 06:28:15 UTC' (from MariaDB 11.5, 64-bit platforms only).

Where did you get the dates from? Do you have a link where one canread about it?

And what kind of fix happend in PHP 8.3?

from phpmyadmin.

This is not a bug, just the tooltip in Typs.php needs to be updated. E.g. to:

case 'TIMESTAMP':
    return __(
        'A timestamp, range is 1970-01-01 00:00:01 UTC to 2038-01-19 ' .
        '03:14:07 UTC on 32-bit platforms (MariaDB 11.3 and earlier), ' .
        'and up to 2106-02-07 06:28:15 UTC on 64-bit platforms (MariaDB 11.5 and later), ' .
        'stored as the number of seconds since the epoch (1970-01-01 00:00:00 UTC)'
    );

from phpmyadmin.
