This year's Sony E3 press conference happens in the middle of the night: 1am (BST - UK time) Tuesday, 7th June.
That's 5pm for people at the Los Angeles Memorial Sports Arena, where the conference takes place.
Sony's entire press event lasts five hours until 10pm their time, 6am UK time.
The actual conference will likely take no longer than an hour-and-a-half, judging by previous years' performances.
The remaining three-and-a-half-hours will be devoted to a "a special event immediately following the press conference". But what that will be Sony hasn't said. Is it an NGP preview event? Is it a party?
The Microsoft E3 2011 press conference takes place on Monday, 6th June at 6pm (BST - UK time).
The Nintendo E3 2011 press conference takes place on Tuesday, 7th June at 5pm (BST - UK time).
