Dates
These functions allow to get the date and time from the server where the application is running. These functions format the date and time in many different ways.
<?php
$dt = new DateTimeImmutable('2015-11-01 00:00:00', new DateTimeZone('America/New_York'));
echo 'Start: ', $dt->format('Y-m-d H:i:s P'), PHP_EOL;
$dt = $dt->add(new DateInterval('PT3H'));
echo 'End: ', $dt->format('Y-m-d H:i:s P'), PHP_EOL;
?>
