Bug description: new DateTime doesn't work well with @timestamp and timezone
Description:
------------
DateTime constructor fails to work well for me when using timestamps
and time zones.
$d = new DateTime('@1192864176', new DateTimeZone('America/
New_York'));
echo $d->format(DATE_RFC3339);
// outputs 2007-10-20T07:09:36+01:00
// why not -04:00?
$d = new DateTime('@1192864176', new DateTimeZone('Antarctica/
Vostok'));
echo $d->format(DATE_RFC3339);
// outputs 2007-10-20T07:09:36+00:00
// why not +06:00?
Besides it reports New York to be shifted +1 from UTC, it returns
unadjusted time - it's 7 AM in UTC+1 and 7AM in UTC+0.
A timestamp is always in UTC, but the resulting DateTime should be
adjusted according to the given time zone in my opinion.
My system clock and TZ environment variable are set to UTC.
Reproduce code:
---------------
$d = new DateTime('@1192864176', new DateTimeZone('America/
New_York'));
echo $d->format(DATE_RFC3339);
$d = new DateTime('@1192864176', new DateTimeZone('Antarctica/
Vostok'));
echo $d->format(DATE_RFC3339);
Expected result:
----------------
// 2007-10-20T03:09:36-04:00
// 2007-10-20T13:09:36+06:00
Actual result:
--------------
// 2007-10-20T07:09:36+01:00
// 2007-10-20T07:09:36+00:00
