What are some potential pitfalls when comparing times in PHP?

When comparing times in PHP, a potential pitfall is not taking into account timezones. To ensure accurate comparisons, always set the timezone before comparing times. This can be done using the `date_default_timezone_set()` function with the desired timezone as a parameter. 

// Set the timezone to the desired timezone
date_default_timezone_set('America/New_York');

// Compare times after setting the timezone
$time1 = strtotime('10:00:00');
$time2 = strtotime('12:00:00');

if ($time1 < $time2) {
    echo 'Time 1 is before Time 2';
} else {
    echo 'Time 1 is after Time 2';
}
