Breaking Changes
When you do not specify a timezone, now
:ref:Time::createFromTimestamp() <time-createfromtimestamp> returns a Time

If you want to keep the timezone UTC, you need to call setTimezone('UTC')::
use CodeIgniter\I18n\Time;
$time = Time::createFromTimestamp(1501821586)->setTimezone('UTC');
