What potential bug related to direct access to DateTime property 'date' is discussed in the thread?

The potential bug discussed in the thread is related to direct access to the DateTime property 'date'. When accessing the 'date' property directly, it returns a DateTimeImmutable object instead of a string representation of the date. This can lead to unexpected behavior or errors in the code if the developer is not aware of this difference. To solve this issue, developers should use the format() method to retrieve the date in the desired format as a string. This ensures consistent behavior and avoids potential bugs related to direct access to the 'date' property.

$date = new DateTime();
$dateString = $date->format('Y-m-d');
echo $dateString;
