Bug description:DateTime hour incorrect during DST jump forward using setTime

Description:
------------
When using DateTime::setTime() and setting the time to a time that
doesn't exist (during a DST jump forward), the timestamp is correct, but
the hour does not move forward.

Test script:
---------------
$tz = new DateTimeZone('America/Chicago');
$date = new DateTime('2020-03-08 01:00:00', $tz);
$date->setTime(2,0);
var_dump($date->format(DateTime::ATOM));

Expected result:
----------------
string(25) "2020-03-08T03:00:00-05:00"

Actual result:
--------------
string(25) "2020-03-08T02:00:00-05:00"
