How to go from mktime to datetime object?

[bugtesting]

I have an mktime that I want to have return a datetime object. The best way I came up with seems way too convoluted:\[code\]DateTime::createFromFormat("Y-m-d H:i:s",date("Y-m-d H:i:s",mktime(0, 0, 0, $data[$j]['month'], $data[$j]['day'],$data[$j]['year'])));\[/code\]any better ways?
