Description

Hi, I found issue with the timestamps in some channel groups of the .mf4 read by asammdf. As an example in the first pictures shown below, the timestamps are not monotonic, which looks correct when reading the file using Matlab codes - see the last picture.

Guess there was something going wrong when reading the file, but not sure what happened. Most channel groups are normal.

Without a file I can't do anything
