>We might add that Eastern Standard Time is 5 hours behind GMT, so EDT would be 4 hours behind GMT. Am I right in thinking that the English also set their clocks ahead in Spring? If so, we're 5 hours behind you always, except maybe around the time when the clocks are moved, since you might pick a different weekend.

My almanac says they do use 'D' time, but at different start/end dates. I guess they call it something different than 'D', since he didn't know what it was...I see that many southern hemisphere nations use daylight time too, but they set it the opposite way we do - that must be confusing to translate :)
