Just kidding! You got the number correct and those of you who're in the same time zone as me, will realise that the number is actually the reverse of the time at which Chukchi posted to say that my guess was correct.

And I pointed that out to you guys, to rub it in the faces of those of you who are in the same time zone as me. The number was in front of you (albeit backwards) all this time! Wee!
