Doctor Who will be pushed back to 20.30 GMT on BBC1 from The Caretaker on 27 September 2014
The Caretaker (and the rest of series eight) will thus be an hour later on ABC simulcast;, so Sunday 28 September approximately 03.30 Western Standard Time, 05.00 Central Standard Time and 05.30 Eastern Standard Time. Times may vary on broadcast.
Plus daylight savings in SA, NSW, Victoria, Tasmania, ACT and Lord Howe Island (which goes forward 30 minutes rather than an hour) from Sunday 5 October 2014 ... but not in NT, WA or Norfolk Island. So -- 03.30 WST ... 05.00 CST (NT) ... 06.00 CDT (SA) ... 06.30 EDT. And 05.30 Norfolk Island, 06.00 Lord Howe Island.
