The issue is that the time zone of Vilnius, Lithuania is wrong. When I set up GoToWebinar I can find Vilnius along with Sarajevo, Skopje, Sofija, Warsaw, Zagreb, however Vilnius is not GMT +2, but GMT +3 (Summer time).
This leads to many webinars being set up incorrectly within our organization. Please, help. Vilnius must be placed in GMT +3.
