We are using UTC guys, not GMT. GMT is the time zone of London which is subject to DST and therefore changes by an hour twice a year. UTC is London time zone without DST, so it doesn't change during the year. We're using UTC to have a constant, unchanging clock so everyone knows what time the contest finished.
