I discovered that Resscan includes several sample data files for various types of machines. I imported the S9 example as another patient and then looked at the graphs. Guess what? Resmed's own detail data file, the rlk files in the patient folder, has a ~40 minute skew when I look at it with the nav window set to 8 hrs and the detail window set to 5 minutes, the same skew I see on my data. Now, you really don't think Resmed would include defective data in the Resscan installation, do you?
Also, if you look at flow and events in the same window, either nav or detail, you will see they are lined up perfectly. The problem is how Resscan applies the timeline to the windows.
S9 data skew - IT HAS TO BE RESSCAN!!!

Re: S9 data skew - IT HAS TO BE RESSCAN!!!
OK, it's time for a mea culpa. I failed to go back to DreamDiver's original post to make sure I was seeing the same problem he described. I'm not. What I am seeing is a timeline disconnect between the nav screen and detail screen that shows up regardless of what data set I'm looking at. The problem DreamDiver discovered, and as shown in his original posted screen shots, is a time shift clearly visible in both screens between an event and the corresponding flow. I have Resscan 3.12. In my case there is no time difference between the event and flow when viewed in the same window.
So, it appears we have two issues, time difference in the original data as DreamDiver so well described and discussed, and a display problem with Resscan that I'm seeing.
Again, I apologize for confusing the problem I'm seeing with the problem DreamDiver made known.
