My setup is using Skyport V1 and PSDK v1.5.3 and I am successfully subscribing to three messages, T_UavAttitudeMsg (10hz), T_GPSInfoMsg (1Hz), and T_baroHeightDataMsg (1Hz).  That push data is getting into my payload which is great but this brings me to my next question.  
How do I know when that data was valid?  There is no timestamp in each of the message structures.  How am I supposed to time align the three data messages?  They don't have to be at the same exact valid time but I need some time to interpolate with.
