Just grabbed the tz stuff for the first time in a year or two. My understanding of Clive Feather's post, which I no longer have a copy of, is that Cheriton Terminal runs on Concession Time (Concession comes from the "Channel Tunnel Concession") - the station clocks are set to Concesion Time. Concession time is formally defined to be the same as French Civil Time and uses the distinctive :) abbreviations of CT in the winter and CT in the summer. I am not sure about the police issue. There are special Rail Transport Police but I believe it's rare for them to be permanently located at a station. The normal police may also be called in to deal with matters. I'd expect the normal police would go by GMT/BST since they're trained to check their watches. I'd expect an RTP who had to travel to the terminal to deal with an incident to use GMT/BST for the same reason. If there are RTPs permanently stationed at the terminal, it could be that they'd set their watches to CT but it's anybody's guess how they'd record times. Anyway, it is a fact that the terminal operates on Concession Time. As such, if they have any Unix boxes there it's likely that they will be configured to run on Concession Time by pretending they're in the Europe/France timezone. We don't need a Europe/Concession zone but I think it's a nice touch to have one. At the very least, knowing about Concession Time is useful for astounding people in pubs. :) -- Paul
