DAQ analog queueOutputData -> how to get the time?

I'm creating some analog voltage Outputs with MATLAB with the command

queueOutputData(s,OutputData);

I will start this with

s.startBackground

My problem is now, that we also want to send some CAN Messages on the same time channel.

Is there a way to get the time out of the running Queue so that I can trigger the CAN Messages on the same time?
