Are there any potential issues with using DateTime objects to calculate date differences in PHP?

One potential issue with using DateTime objects to calculate date differences in PHP is that the result may not always be accurate due to differences in timezones or daylight saving time adjustments. To ensure accurate date differences, it is recommended to use the `diff` method of the DateTime object, which returns a DateInterval object representing the difference between two dates. 

$date1 = new DateTime('2022-01-01');
$date2 = new DateTime('2022-01-15');

$interval = $date1->diff($date2);
echo $interval->format('%R%a days');
