DateInterval Format

Example

// Can be also DateTime object
$date = new DateTimeImmutable('2021-05-12 13:43:10');
$interval = new Interval\Interval('-P1D|23:59:59');
$newDate = $interval->getDate($date); // Will return new object
echo $date->format('Y-m-d H:i:s') . ' => '.$newDate->format('Y-m-d H:i:s') . "\n";

Will output

2021-05-12 13:43:10 => 2021-05-11 23:59:59

$date = new DateTimeImmutable('2021-05-12 13:43:10');
$interval = new Interval\Interval('P15D|14:00');
$newDate = $interval->getDate($date);
echo $date->format('Y-m-d H:i:s') . ' => '.$newDate->format('Y-m-d H:i:s') . "\n";

Will output

2021-05-12 13:43:10 => 2021-05-27 14:00:10

$date = new DateTimeImmutable('2021-05-12 13:43:10');
$interval = new Interval\Interval('-P5D');
$newDate = $interval->getDate($date);
echo $date->format('Y-m-d H:i:s') . ' => '.$newDate->format('Y-m-d H:i:s') . "\n";

Will output

2021-05-12 13:43:10 => 2021-05-07 13:43:10
