I don't know how you're determining peoples timezones, probably geolocating by IP address, but my timezone is incorrect. When I specify a time to run a game it sets the timezone to ADT when my timezone is actually AST. There's an hour different. Please see my suggestion on letting us have a default timezone using current methods for determining timezone but letting us change timezone in account settings: <a href="https://app.roll20.net/forum/post/6291850/let-us-specify-our-timezone-in-account-settings" rel="nofollow">https://app.roll20.net/forum/post/6291850/let-us-specify-our-timezone-in-account-settings</a>
