In what situations should one consider extending the time calculation logic to include date factors in PHP?

When dealing with time calculations in PHP, it may be necessary to consider date factors when the calculations span across different dates. This is important when calculating durations, intervals, or deadlines that cross over midnight. By including date factors in the time calculation logic, you ensure accurate results and handle edge cases where the time difference includes multiple days. 

// Example of extending time calculation logic to include date factors
$startTime = strtotime('2022-10-01 23:00:00');
$endTime = strtotime('2022-10-02 01:30:00');

// Calculate the time difference including date factors
$timeDifference = $endTime - $startTime;

echo "Time difference: " . gmdate("H:i:s", $timeDifference);
