Where is the script to put timestamps on the GPS track, knowing only the time of the first and last points?

Question

satellite navigation

There is a track without time. There is information about the start time of the track and the end time of the track. You need to put down the time for the intermediate points of the track (according to the average speed).
The bottom line is that there are photos taken on a trip, there is a planned track, but the real track was lost. Now the task is to scatter the photo on the track.
Surely such a script has been written for a long time, therefore, before writing it myself, I decided to ask.
We need a ready-made script, with an entry in gpx or any other format.
