USRP B210 GPSDO time?

I am working on a project using both the USRP B210 and the compatible GPSDO. I am time-stamping pulses detected when going through the SDR. Is there a way through either MATLAB or Simulink that I can pull the GPS timestamps from the SDR packets it streams to the PC? I already have the USRP Communications toolbox installed. I have gone through the toolbox documentation and it appears to have no information regarding parsing the packets. The Simulink block appears to only provide the sample of the signal, and not the timestamp of that sample.

Unfortunately, the ability to get the timestamps of each sample is not currently possible in Simulink.
I have notified the developers of this limitation in Simulink, and they may consider this functionality for a future release.
If the data is indeed in the packets, then one would have to parse the packets outside of Simulink to get the timestamps.
