@TimSchofield There's a worse problem, though. For me, Opera is correctly sending en-AU at the front of the Accept-Language header, in requests it sends to web servers. But it's actually formatting dates as if they're en-US! Web servers are therefore expecting dates in the request data to be formatted the normal way, and get confused by the topsy-turvy US format. This makes Opera unusable on websites that use browser-dependent date inputs, which more and more do these days.
