Timestamps within mosaics from original images?

I have two mosaics of thermal images taken from two different flights, and I’d like to make a map of the rate of cooling/heating using the changes in temperatures and the appropriate time differences. The problem is the flight durations are not exactly the same, so the time difference between the two mosaics is not totally constant for every location in the scene. Is there some way to make “timestamp maps” for the two mosaics, so that I can calculate a time difference for each pixel in the scene?

Hello there, This is not possible using PIX4Dmapper software. Let see if someone had an idea to resolve the issue.
