I'd like to log my time using the actual time of day. For example, the door closes at 19:22 and the door opens at 21:57. According to my company that is the time I can log as flight time and is what I get paid for. Can log book pro calculate this for me? How do I set it up? I read a support article about this and it said to click on the word "Duration" in window mode to toggle decimal time or hours and minutes. I do have the latest version and this feature does not work.
