What are the potential drawbacks of storing dates in the format [YYYY.MM.DD - HH:MM] in a MySQL database?

Storing dates in the format [YYYY.MM.DD - HH:MM] in a MySQL database can make it difficult to perform date-related calculations or comparisons. It is recommended to store dates in the standard MySQL date or datetime format (YYYY-MM-DD or YYYY-MM-DD HH:MM:SS) for better compatibility and easier manipulation.

// Example of converting a date from [YYYY.MM.DD - HH:MM] format to MySQL datetime format
$date = "2022.01.15 - 14:30";
$mysql_date = date("Y-m-d H:i:s", strtotime(str_replace([".", " - "], ["-", " "], $date)));
echo $mysql_date;
