What are the potential performance issues associated with using a counting method to calculate time differences in PHP?

Using a counting method to calculate time differences in PHP can lead to performance issues, especially when dealing with large datasets or frequent calculations. To improve performance, it is recommended to use built-in PHP functions like `strtotime()` and `date_diff()` to accurately calculate time differences efficiently. 

$start_time = strtotime('2022-01-01 12:00:00');
$end_time = strtotime('2022-01-01 12:30:00');

$time_diff = date_diff(date_create('@' . $start_time), date_create('@' . $end_time));

echo $time_diff->format('%H:%i:%s'); // Output: 00:30:00
