UK is currently on GMT, if its easier for the rest of the world we could just always keep the KO on GMT so that wherever you are you only need to know the time in GMT. Of course, UK & Europe would need to adjust to a clock change twice a year, but maybe keeping the KO on a world-constant would be the way to go on.
(part of the reason it previosuly followed uk time at 10am was becuase I was the main admin every week and 1hr later would have made it impossible for me to do it on some weeks).
