Times are really messy... Same website manages to use both CET and CEST in different pages (fortunately both figures "correct" though, but unfortunately most times don't mention the zone at all ), and even manage to disagree by 30mins when it comes to time of 1st attempt and start of webcast...

So it looks like 1st attempt is at 0800 or 0830UTC and webcast starting an hour earlier.

(I think i'll wear my tinfoilhat whole day just to be sure. No idea how it could help save the world but i figure the propability of it working is not zero.)
