fix: prevent generate not UTC datetime
This value object was thinking for use UTC as TimeZone standar. However, it allow set other timezone by passing it on "from" factory:
$date = DateTimeValueObject::from('2025-01-10T15:16:11+01:00')
echo $date->format(\DATE_ATOM) ; // result 2025-01-10T15:16:11+01:00Before this fix, date was transformed to UTC, expected result: 2025-01-10T14:16:11+00:00
