Just pushed an update to the site with many timezone related fixes.
@Daer007 Thanks for the bug report. The calendar is now taking your timezone into consideration, shifting events to the next or previous day when needed.
@RolandHuxley The timezone list has been expanded to cover the globe. I have tried to select only the biggest city in each timezone so the list doesn't get too long. I believe Australia is spread over 3 zones so either Hong Kong, Tokyo or Sydney should be yours.
@tx1ndoki Tokyo is now available.
@NoorElBahrain The summer-winter time transition, or lack thereof, should be applied automatically. If it doesn't please let us know.
