This morning a new fix went out to our web servers. One of the most long standing and annoying bugs in event scheduling, where the final page would show a different zone than the one you began listing in, should now be fixed.
If you still experience this issue, please open a Help Central ticket by going into Help from There Central and then click on 'Ask a question' to report the occurance. In your report, include all information such as the zone you started scheduling in, the time you started scheduling, and the zone the event eventually ended up on the final confirmation screen.
