Working in the UK time zone isn't that hard, I would recommend Havoc 3 as they do their operations on Saturday Night / Sunday mornings and a few of the squads in the platoon do training prior to the operation (Around 6-7pm GMT), if you don't work on Sundays its not a problem going to bed at 3-4am.
We still have some Brits in Sunday Platoons (myself included), it's not that bad especially being in University where I have no lectures on Monday anyway. The unit operates in EST time, so be prepared to set alarms on your phone if you need to go to something, I made an EST clock on my desktop that helps:
If you end up joining and want my code for the clock let me know. (anyone is welcome to have it anyway)
We could do with more Brits so don't let the timezone throw you off.
