Hi,
the method Survey::getState() can return the state 'willRun'; apparently 'willRun' should return when the survey is active and the start date is in the future. If the survey is active without a start date it should return 'willExpire'.
The code says:

// now with timeadjust correction
$sNow = date("Y-m-d H:i:s", strtotime(Yii::app()->getConfig('timeadjust'), strtotime(date("Y-m-d H:i:s"))));
...
// null if start date is empty
$sStart = ($this->startdate != '') ? date("Y-m-d H:i:s", strtotime(Yii::app()->getConfig('timeadjust'), strtotime($this->startdate))) : null;
...
// now without any correction if $sStart is null
$oStart = new DateTime($sStart);
...
// inconsistent, $oStart could be before o after $oNow based on correction
$bWillRun = (!is_null($oStart) && $oStart > $oNow);

I think the last line should be:
$bWillRun = (!is_null($sStart) && $oStart > $oNow);
