What potential issues can arise when sorting DATETIME values in MySQL when the date format is not standardized or converted properly?

When sorting DATETIME values in MySQL, potential issues can arise if the date format is not standardized or converted properly. This can lead to incorrect sorting results, as MySQL may not recognize the dates in the non-standard format. To solve this issue, it is important to ensure that all dates are in a standardized format (such as 'YYYY-MM-DD HH:MM:SS') before sorting. 

// Convert non-standard date format to MySQL standard format before sorting
$date = '10/25/2021 15:30:00';
$standard_date = date('Y-m-d H:i:s', strtotime($date));

// Use the standardized date in the MySQL query for sorting
$query = "SELECT * FROM table_name ORDER BY date_column ASC";
