Polar Orbiting Time Stamps

The polar orbiting data is very nice.  However, the time stamp is confusing.  In the image below, the NUCAPS improved latency product has a time stamp of 19:41Z.  However, it shows that for ALL of the points. In reality, each point has a different time stamp as the satellite moves across the Earth.
In the experiment at this time, I was concerned with Wyoming.  The pass occurred at 19:49Z (per the NPP SSEC orbit site).  But the time labeling gave the appearance it was at 19:41Z.  Each point should have the approximate time the pass occurred, ideally in the Skew-T.
