The only thing I see wrong is the dates in the Expected Result. Like, GMDATE
and
GMT should be the same time...

The actual results are absolutely fine, e.g.
> UTC: 2010-07-06 02:58:03
> JST: 2010-07-06 11:58:03 (UTC +9)
UTC+9 means, add 9 hours to the time expressed as UTC and you
get the local time (JST).
IMHO this is not a bug.

or is it design?
so example...,
EST: 2010-07-05 21:58:03 (-5h)
UTC: 2010-07-06 02:58:03 ( 0h)
JST: 2010-07-06 11:58:03 (+9h) * local timezone.
strtotime("EST");
-> (localdate+EST) "2010-07-06 11:58:03 EST"
-> (convert UTC) "2010-07-06 16:58:03 UTC"
-> (timezone:JST) time-value on "2010-07-06 01:58:03 JST"

$tz = date_default_timezone_get();
$jst = date("Y-m-d H:i:s", strtotime("JST",$now));
$gmt = date("Y-m-d H:i:s", strtotime("GMT",$now));
$utc = date("Y-m-d H:i:s", strtotime("UTC",$now));
$est = date("Y-m-d H:i:s", strtotime("EST",$now));
$edt = date("Y-m-d H:i:s", strtotime("EDT",$now));
