The touchdown time is 10:10 and the flight of 1:04 started at 9 so you've not gone over a timeline - butnow your next flight is at 9am again? The only way to do that is if you used the Flight Gen time controls or you moved your profile back an hour.
I've been making flights and checking the code, it's only going to "add time" to the present "profile time" or it's going to make the flight at the "time shown" in the Flight Gen page.
