DateTimeImmutable::setTimestampSets the date and time based on a Unix timestamp


public DateTimeImmutable::setTimestamp(int $timestamp): DateTimeImmutable

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

Note that this is not the right way to initiate a \DateTimeImmutable object with a numeric Unix timestamp. 

// Wrong, despite the documention *kind of* alluding to it
$obj = \DateTimeImmutable::setTimestamp(time() - 1);

// Also won't work
$obj = new \DateTimeImmutable(time() - 1)

// Correct, works, clean single line
$obj = (new \DateTimeImmutable())->setTimestamp(time() - 1);

... In fact, this is a non-static method and thus should not be called statically.
