battle of planets reset?

You have a set number of games to accumulate as many points as you can in a given week, starting at 12:00:00 am Sunday and finishing at 11:59:59 pm Saturday.

Pokerstars is in GMT -5 which is Eastern time, right now it's daylights saving time so that would make Pokerstars GMT -4 http://www.pokerstrategy.com/strategy/mtt/1860/1/
So in GMT the BOP resets on Saturdays night at 4:00 GMT or in Sundays early morning at 4am GMT(it depends if you call it an early morning or still the night)
I think I did the conversion right, you can also just set the Pokerstars clock to Eastern time (ET) and then you will have the server time.
Edit: I noticed that you are in the UK so you are now GMT+1 that means for you it will end at 5am.

Thanks a lot Krishjanis much appreciated...

i couldn't find it on the website probably due to the large quantity of bourbon i have consumed
