The first one is good to me.
Most people will be in the following timezones:
Pacific Time PDT (GMT -8)
Central Time CDT (GMT -6)
Eastern Time EDT (GMT -5)
UK BST (GMT)
EU (GMT +1)
Japan (GMT +9)
Australia (GMT +10)
We have to assume most players are in the US, so if an event is 4pm EDT then this translates to:
Pacific Time PDT* (13:00, 1pm)
Central Time CDT* (15:00, 3pm)
Eastern Time EDT* (16:00, 4pm)
UK BST* (21:00, 9pm)
EU* (22:00, 10pm)
Japan (05:00, 5am)
Australia (06:00, 6am)
