I would assume that legal GMT in the UK in the year 2011 is exactly the same as UTC. I could not find a law for that.
No, the law here says legal time is GMT, but most official time signals are UTC. There have been a few unsuccessful attempts to deal with the mismatch between de jure and de facto UK time, e.g. http://www.publications.parliament.uk/pa/ld199798/ldhansrd/vo970611/text/706...
So there is one flavor of GMT that is UTC and there is legal GMT which is something different. 2011i/tzdata equates GMT for 2011 with UTC. I would now reply to the former text: On Sat, Sep 24, 2011 at 3:53 AM, Steve Allen <sla@ucolick.org> wrote:

So if country A says its legal time is an hour ahead of GMT and B says they are an hour ahead of UTC, those are technically different statements. However, to the approximation of tzdata, the outcome is the same: both country A and B would be shown in the tzdata file as having an offset of 60 minutes.
Is that correct?
It is correct under ITU-R TF.460-6. To my understanding the statement of country A is ambiguous. Whether there is approximation in tzdata depends on how one interprets the the statement of country A. This has nothing to do with ITU-R TF.460-6.
