Another usefull method you may need is calculateEndTime. Each service can have its own duration, also your company's employees possible have different work schedule form day to day. So using this method you can show to a client an end date and time of the service he've booked in a correct way.

Code example of calculating booking end time

$startDateTime = '2015-03-03 09:00:00';
$serviceId = 1;
$performerId = 1;
$availableTime = $client->calculateEndTime($startDateTime, $serviceId, $performerId);
// returns '2015-03-03 10:00:00'
