It would be interesting to find reliable indicators about whether UTC or GMT is the basis in any given region. Even recently I've seen official decrees using the geographic terms "meridian" and "Greenwich".
UTC used in EU law to define the start and end of summer-time: http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:C:2011:083:0006:01:...

I've done this before: there's a horrible mix of GMT and UT in the different translations of that Directive, including some ambiguous cases. And the translations don't necessarily match the legal times in the countries using those languages. -- Clive D.W.

Since they are the same thing, one is just an older name, why does this matter? If you want to use a single consistent term, sure, stick to UTC. But other than that, if you say GMT you mean the same time as if you say UTC. paul -----Original Message----- From: Clive D.W.

No, but this is not the list to discuss that.

GMT is *not* the same as UTC. Of the 22 languages that 2000/84/EC is officially written in: * 13 (BG CS EL EN ET FI HU LT LV MT PL SK SV) use "GMT" or "Greenwich"; * 7 (DE ES FR IT NL PT RO) use "universal time"; * 2 (DA and SL) use "UTC". Note that legal time in Germany is based on UTC while in Austria it is based on GMT. Denmark is "solar time for 15 degrees East". -- Clive D.W.

The above link leads to a 2011 communication related to directive 2000/84/EC. The 2000/2001 has indeed varying translations of the article 2: == EN English == http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2001:031:0021:002...
From 2002 onwards, the summer-time period shall begin, in every Member State, at 1.00 a.m., Greenwich Mean Time, on the last Sunday in March
