Objektorientierter Stil


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

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

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

Prozeduraler Stil


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

date_time_set($date, 14, 55);
echo date_format($date, 'Y-m-d H:i:s') . "\n";

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

Oben gezeigte Beispiele erzeugen eine ähnliche Ausgabe wie:

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

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


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

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

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

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

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

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

Be aware that setTime can cause a change in the timezone offset: https://3v4l.org/MqYN9

(The time 01:05:00 exists twice on this day in Europe/London due to DST change - once in +01:00 and then again at +00:00)

$tzUK = new \DateTimeZone("Europe/London");
$tzUtc = new \DateTimeZone("UTC");
$dt = \DateTimeImmutable::createFromFormat("!Y-m-d H:i:s", "2020-10-25 00:05:00", $tzUtc);
$dt = DateTime::createFromFormat('U', $dt->format('U'));

print $dt->format(\DateTime::RFC3339 ." e") ."\n";

$dt->setTimeZone($tzUK);

print $dt->format(\DateTime::RFC3339 ." e") ."\n";

$dt->setTime((int) $dt->format('H'), (int) $dt->format('i'), 0);

print $dt->format(\DateTime::RFC3339 ." e") ."\n";

Will output:
2020-10-25T00:05:00+00:00 +00:00
2020-10-25T01:05:00+01:00 Europe/London
2020-10-25T01:05:00+00:00 Europe/London

Verified on PHP 5.3 thru 8.0 (latest at time of posting)
