@ poisondartfrog - I checked my time zone, but we have winter and summer time here. ATP gives a lot of opportunities to fill in that. I was on 'French summer time' that should be the same as in Belgium. But when I checked that with your time tables I get confused. There are so many time table I can choose on ATP, but they are not really clear to me.
I'm in GMT +1
Can you translate that to the starting hour of the swap?
