Version Description

7.1.0 The microsecond parameter was added.

Examples

Example #1 DateTimeImmutable::setTime example

Object-oriented style

<?php
$date = new DateTimeImmutable('2001-01-01');

$newDate = $date->setTime(14, 55);
echo $newDate->format('Y-m-d H:i:s') . "\n";

$newDate = $date->setTime(14, 55, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";
?>

The above examples will output something similar to:

2001-01-01 14:55:00
2001-01-01 14:55:24

Example #2 Values exceeding ranges are added to their parent values

<?php
$date = new DateTimeImmutable('2001-01-01');

$newDate = $date->setTime(14, 55, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";

$newDate = $date->setTime(14, 55, 65);
echo $newDate->format('Y-m-d H:i:s') . "\n";

$newDate = $date->setTime(14, 65, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";

$newDate = $date->setTime(25, 55, 24);
echo $newDate->format('Y-m-d H:i:s') . "\n";
?>

The above example will output:

2001-01-01 14:55:24
2001-01-01 14:56:05
2001-01-01 15:05:24
2001-01-02 01:55:24
