One simple answer for all your questions;

- Any match must be played on the scheduled day. A day in T11 starts at 3:30 GMT and ends at 1:30 GMT.
- If you are from Wisconsin you can change your home games to anytime from 22:30 to 20:30 of the following real life day.
- However you can not set a game for a time less than 3 hours before or after another match (whether it's a match of yours or of your opponent).
- Period to change a match time:
--Antecipation: You can't bring forward a game any more if it's going to take place within the next 24 hours.
--Postponing: You can't postpone a match if you are just 1h away from the start.
