To anyone who is having this issue. If you are getting the wrong Timezone for scheduling, check your device to assure that even though its setting might be automatically set for your Timezone, the manual setting might not be. I found this issue with my notepad of nearly 4 years old. It was set for Eastern time manual, though it was automatically adjusting itself to Central time. To fix it, just manual set the timezone correctly, to get Roll 20 to work properly.
