For those confused on the timezones. Heres some of the general Zones.
Coil = BST US base = EST EU = GMT
If you need to calculate to Coil time. [Based on Clock on Coil Site]]
GMT = 1 hour behind [+1Hrs to Coil Time] eg..if coil is 11am then gmt is 10am EST = 5 hours behind [+5Hrs to Coil Time] eg..if coil is 10am then est is 5am
i find the best way to work out the conversion from est to gmt is to use the link, move over to est time, it says what u move over with your mouse, then since it displays your time, you can see the hour differance.
