Timezones and HBP Release

[Joe Bento]

OK, it's long past bedtime, but I was tossing and turning thinking
about the upcoming HBP release on Friday.

The Half-Blood Prince will be released throughout most of the English
speaking world at midnight local time.

In the case of Australia, they are 10 hours ahead of London.  Britain,
of course is what we might consider ground zero for Harry Potter.  So
will people in Sydney be reading the HBP while it is still only 2pm in
London?
