Hristo!!
Glad to hear from you.. the train you kicked into motion is still chugging along.
Sundays the SEA runs 'snapshots' and Scenario Lites. It's booked as far as I know. The Arena will be available on the Saturdays at the times and dates specified.
As far as the time goes, perhaps you are unaware that most of the pilots on both sides are from here in the USA.. and that 3:00 PM GMT is 5:00 AM in the USA on the west coast. This is hugely inconvienient for the USA pilots. Assuming they'd like to be awake for the fight, this means they'd have to haul themselves outta bed at 3:30 am on a Sunday morning. Where I am; in the Eastern time zone, I hauled my bellybutton outta the sack at 6:30 am for our first duel. 7 cups of coffee did little to cure my pre-flight jitters.

Since in Croatia, you are at +1 hour GMT, and the Central USA is -6 hours GMT, we'd be flying on our Saturday afternoon, and you'd be flying on your Saturday evening. Or did I get this backwards?
