I do for half the year, being British. At work we have two local relevant times in the office - GMT and Europe/London. Some programs are scheduled at GMT (world service), sometimes they're in UK time (national news). Some computer logs are in GMT, some are in local time. It's a right pain - if we were 4 or 5 hours offset from GMT it wouldn't be a major problem, you tend to know roughly what time you're looking at, and you'd only have wall-time or GMT. GMT and BST are too close together to be unambiguous though. Colleagues working in Washington tend to be 5 hours behind regardless, those in singapore are 7 or 8 ahead. Some countries I give up with completely Specified GMT or UTC doesn't always halo as some people assume you mean "time in London". UTC is better in that regard, but it would be easier if UTC was several hours away from civil time.
