Timezone calculation error

In _announcements_unixtime2drupaldate, the time is decremented by the address of _announcements_get_timezone. It should be incremented by its return value:

function _announcements_unixtime2drupaldate($unixtime) {
// $unixtime -= _announcements_get_timezone;
$unixtime += _announcements_get_timezone(); /* BUG FIX */
return array('day' => gmdate('j', $unixtime),
'month' => gmdate('n', $unixtime),
'year' => gmdate('Y', $unixtime));
}
