It's based on a location and season, same as UTC. It's based on Greenwich in winter, not Greenwich in summer. Greenwich in summer is GMT+1. That is a fact, look it up. UTC was designed so it coincided with GMT. It was modeled after GMT.
There's more. Not all countries switch by an hour, some only by 30min. And some countries switch in several intervals, not just twice. And none of that matters, because all of that applies to both GMT and UTC. Daylight savings has nothing at all to do with either. It just means all countries push their times back or forth by a certain amount during certain periods, whether they call it GMT+1 or UTC+1.
Again, I'm not even disagreeing with you, they should be using UTC. But it does not matter, no one will notice any difference, because the absolute only time difference between the two is in the subsecond range (at any given time of the year, at any given position on the face of the earth).
It's 9:47AM GMT.
