What potential issues can arise when using substr() or explode() functions to manipulate date and time data in PHP?

When using substr() or explode() functions to manipulate date and time data in PHP, potential issues can arise if the date format changes or if the data is not formatted consistently. To solve this issue, it is recommended to use PHP's built-in DateTime class, which provides methods for parsing and manipulating date and time data in a more reliable way. 

// Example of using DateTime class to manipulate date and time data
$dateString = "2022-01-15 08:30:00";
$dateTime = new DateTime($dateString);
$formattedDate = $dateTime->format('Y-m-d H:i:s');
echo $formattedDate;
