No, Greenwich Mean Time is just the standard time in reference to which all times are calculated but the whole time zone is not "called" *GMT*. GMT doesn't follow daily saving and such. In a week's time you'll be in the +1 time zone because of that. Right now your local time matches GMT but as I said above GMT is simply the standard time (also called Universal Time), not a time zone.
