Oh, yes I completely misinterpreted that sentence. Derf. I was led astray by the coincidence that CEST is +0200 and CET +0100. ijs ________________________________ From: Alexander Belopolsky <alexander.belopolsky@gmail.com> Sent: Wednesday, August 26, 2015 16:21 To: ISAAC J SCHWABACHER Cc: Guido van Rossum; datetime-sig Subject: Re: [Datetime-SIG] DST explained visually On Wed, Aug 26, 2015 at 5:04 PM, ISAAC J SCHWABACHER <ischwabacher@wisc.edu<mailto:ischwabacher@wisc.edu>> wrote:

My favorite part of that Wikipedia article is this sentence: "Sie darf nicht verwechselt werden mit der international üblichen Abkürzung der Zeitzonen, nach der 2 Uhr MESZ als 0200B und 2 Uhr MEZ als 0200A bezeichnet werden." Which is to say (IIUC) that the international standard is that the first occurrence is B and the second is A, exactly the opposite of the German system. O Weh! I think they just caution you not to confuse the "A" and "B" times with the (military) letter zones A through Z. The fold disambiguation seems to be in the natural A first, then B order.
