time zone converting

[astralaaron]

I have been up all night trying to figure this out, please point out what I am doing wrong!

$laTimezone = new DateTimeZone('America/Los_Angeles');$nyTimezone = new DateTimeZone('America/New_York'); // viewer is in NY and should see what time in NY it will be when it is 4:40 in LA.$laDateTime = new DateTime('2014-02-05 16:40', $laTimezone); //user scheduled for 4:40 Feb 5th (LA TIME ZONE)$offset = $nyTimezone->getOffset($laDateTime);$nyDateTime = date('Y-m-d H:i', $laDateTime->format('U') + $offset);echo $laDateTime->format('Y-m-d H:i') . ' in (LA) is ' . $nyDateTime . ' in  (NY) ';

Basically, someone posts a "meeting" time in Los Angeles at 2014-02-05 16:40. Someone in New York browsing the posts sees the meeting from Los Angeles, but instead of 2014-02-05 16:40, they see 2014-02-05 19:40 because that is what time it will be in NY when it is 16:40 in LA.

 

I can't seem to get it working the way I want it.

 

EDIT:

here is the output:

2014-02-05 16:40 in (LA) is 2014-02-05 12:40 in (NY)

Why not create another DateTime object and set it to the same Unix timestamp, but set it to the other timezone?
