In the last version I could use timeskip. I hate dark on the Mars and when it getting dark, I just timeskip 12-14 hours and I could work in daylight. But in version 0.8.0170, skip only one hour when I set the skipper to +11 hour.
Oh, and itás in game mode, not hard mode.
In my currenct situation 17:30 at mars and 8:30 at Earth Controll Center. Then I set the skipper to +11 hours and press the Time Skip button. Animation starts and when it's done 9:30 at Earth and when I connect to my rover on Mars there is 18:30.
