Ok. I'll give you that - I wasn't standing on GMT - lol, that'd be funny come to think of it I guess I am a bit tired now... But the meridian crosses at the same line, doesn't it? And it's there, in Greenwich, too. Right? So, it was the meridian I was standing on?

Oh dear, I shouldn't be writing any essay at this time - my brain just isn't working anymore at all...
