Description:
------------
This is just a simple request for a feature of the built in time() for PHP or a new function completely.

I think a timezone offset argument for this function would be great. Let's say I want to find the GMT -6 but my server is located in GMT -8, here is an example pice of what the function should automaticly do: (see attached code)

The function simply returns a timestamp of the offset provided in the argument, would be nice to have such an argument exist in the time() function, or a whole new function if adding an argument to time() isn't possiable.

Reproduce code:
---------------
<?php
class MyTimeZone {
   const TIMEZONE_SERVER_OFFSET = -5; // your server's offset from GMT 0
   public function timeOffset($offset = null)
   {
       if (is_int($offset)) {
           $local_offset = $offset - self::TIMEZONE_SERVER_OFFSET;
           return time() + 3600 * $local_offset;
       }
       return time();
   }
}
// Current time in my server's location is 1:07 pm GMT -5
$time = new MyTimeZone();
echo date('h:i:s a', $time->timeOffset(-8)); // finds GMT -8
// The result would look something like this:
// 10:07:42 am
?>
