how to convert timestamp to date in codeigniter

Question

I want to convert 1373892900000 to Monday 2013/07/15 8:55 AM in Codeigniter.

However, I keep receiving a totally different result by converting

Answer 1

Why not just use PHP's date function?

public function time_convert($timestamp){
   return date('l Y/m/d H:i', $timestamp);
}

For different timezones use a DateTime object:

public function time_convert($timestamp, $timezone = 'UTC'){
    $datetime = new DateTime($timestamp, new DateTimeZone($timezone));
    return $datetime->format('l Y/m/d H:i');
}

Think that should work. Note: I tihnk you need at least PHP version 5.20 for the TimeZone class.
