Shakespeare,
I think that you're working bloody hard! I hope, for your sake, that you don't do that many hours every year.
As for bunk time, at BA time in the bunk does count towards your 900 hours maximum per year. It may or may not have alot to do with flying the aircraft - it just depends what you are dreaming about! Seriously though, long range operations are only made possible (and legal) by the provision of adequate horizontal rest facilities for the crew.
