New Timezone Tables
GMT+1 is BST and Portugal
GMT+2 is CEST so most of the Europe (Berlin, Paris, Warszawa)
GMT+3 is Eastern European Time (Kyiv, Moscow)
How it works?
If you are a GMT+1 team, you have to see your time zone row (with the “->“) that is set with a GMT+1 time.
That means if you have to play against a GMT+2 team, the default time will be 22.00 GMT+1 for you and GMT+2 23.00 for your rival.
If you are a GMT team and you have to play against a GMT+3 team, the default time will be GMT 20.00 for you and 23.00 GMT+3 for your rival.
