getUTCHours()?

I’m making a clock for universal time zones. I need to use the “universal” time methods of my date object, but I’m not exactly sure what “universal time” refers to. I had read that it’s simply GMT (which would make sense), but I’m in London (GMT+/-0) and when I trace *getUTCHours() *I’m getting a result an hour behind what it should be.

Any ideas?
