no it means a battle lasts for that time, between 3 servers. there is a persistent scoreboard for that time - individual players can distinguish themselves, on behalf of their server, for a 3 week rolling battle. that sounds good to me. after that the battle ends, servers are awarded ELO-type points according to how they performed. then the next 3 weeks the servers are rematched according to the new league-table rankings. and so on and so forth.
