I've been wondering the same thing, I might get it on Primetime in the UK if I get home in time tonight! I know the Primetime build up starts at 20:00 in the UK. If it's any help (which it probably isn't) I went and looked at a German website selling tickets and it said the event was from 19:00 German time. I assume that includes undercard etc obviously...so the actual fight would be a couple of hours later?
The RTL live covering schedule is from 22:00 to 0:00 hours german time (CET), it's GMT +1. You can expect the fight to actually start somewhere between 22:30 and 23:00 hours, probably closer to 23:00 hours, but it won't be much overdue, because the fight is between the german "Pop Idol" (Deutschland sucht den Superstar) which starts at 20:15 hours but the decision is scheduled for 0:00 hours (live too) and because of the (slight but nevertheless) possibility of chambers going full 12 rounds, they can't let the bout start after 23:00 hours because they wouldn't have much time left between the end of the fight and the "Pop Idol" decision for all the post fight interviewing and analysing etc. they surely plan in excess as usual... So if you don't want to risk to miss the start (or even worse to miss the 1st round KO...), tune in sometime between 22:30 and 22:45 hours
Central time is 3pm, I dont know if Utah is in the Mountain timezone or the Pacific timezone, so either 2 or 1 for ya.
In Germany we have CET (Central European Time) and this is GMT +1 (Greenwitch Mean Time). US time zones are -5 (Eastern) -6 (Central) -7 (Mountain) -8 (Pacific) -10 (Alaska/Hawaii) so for N.Y. its 6 hours difference and for L.A. its 9 hours difference. If you're somewhere in between, then you might have 7 or 8 hours difference, or up to 10 hours in Honolulu, it's up to you to know where you live :think So if the bout starts at 22:45 hours German time (CET) its 16:45 in N.Y. and 13:45 hours in L.A. If I'm correct Utah has Mountain time so it should be 14:45 for you
