The time zone your league plays in. This is used to determine your league's local time, which in turn is used to determine when games are in the past or in the future, as well as for deadlines when reporting game results or making or cancelling referee assignments.
There is a daunting list of possible time zones, so we do not list them all. If your league plays in a time zone that is not listed, contact technical support and let us know which zone you are in. We will add it to the available options.
