I'm probably ignorant and overlooking something. But if the gameday post says noon GMT, it doesn't mean noon London time to me. It means GMT. Iceland time, at this moment. So gameday starts at noon (GMT), 1pm London time (BST) or 2pm Amsterdam time, or 4 AM California time (GMT-8). I use GMT because it is equal to the UTC (coordinated universal time-the common reference unit).
Redbaird is really going to come here and kill me someday, to get rid of those time confusions.
Hehe. You and I are used to GMT. I used to listen to shortwave radio and all reports to the clubs were in GMT. The broadcasters, such as Radio Nederlands, would give their schedules in GMT.
The FA Game Day is not going to start at 1200 GMT, but rather at 1200 London time (BST), or 1100 GMT-Iceland time.
If you want a funny way to think of it, then you can believe that during the Northern Hemisphere Summer, they move the Prime Meridian from Greenwhich to Reyjavik!
