Browser is Firefox 72.0.2, OS is Windows 8.1. System clock is always displaying the correct time, BIOS battery is working. It already happened twice to me that a game's starting time was displayed incorrectly. I assumed I could play these games, applied for them, created characters and wrote backstories for them, scheduled other stuff around so that nothing collides with the planned game. Only to discover shortly before game time that the game starts at a completely different time than Roll20 displayed when I signed up. For example, I joined an oneshot that was displayed for me to start at monday noon, but it now actually happens during the night from sunday to monday, meaning I can't play it, my efforts of character creation are wasted and I could have invited friends for monday afternoon or signed up for other games here on Roll20. Roll20 supposedly converts time into my time zone, displaying every time as GMT+1 (CET, which is my time zone as an Austrian), but probably that sometimes doesn't work correctly and displays a wrong time. Also, it would be great if there was an option to switch to the 24 hours format, which is much less confusing than the am/pm format for people that are not used to it.
