Re: Don't mention the...
I'm not clear on how this works in general, but BBC World Service radio (Europe anyway) broadcasts in English and in Greenwich Mean Time twelve months of the year. I suppose if you're halfway round the globe then converting that to your local time needs knowing how far away Greenwich is and whether you have local daylight saving, which you probably know, but it excuses you knowing whether it's daylight saving in Greenwich, because how would you.
So in this sense at least, Greenwich Mean Time exists while London (except the BBC) is not using GMT.
