Yordamsal kullanım

date_time_set(
    DateTime $object,
    int $hour,
    int $minute,
    int $second = 0,
    int $microsecond = 0
): DateTime

Resets the current time of the DateTime object to a different time.

Like DateTimeImmutable::setTime() but works with DateTime.

The procedural version takes the DateTime object as its first argument.

8.1.0	The behaviour with double existing hours (during the fall-back DST transition) changed. Previously PHP would pick the second occurrence (after the DST transition), instead of the first occurrence (before DST transition).
7.1.0	The `microsecond` parameter was added.

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
