Well Line is Japanese and most of their userbase are Asian (at least those I talk to who use it are Japanese, Thai and Taiwanese). Therefore, the game uses GMT+9 as time zone. I don't think it's targeted towards Americans since neither the game nor Line does any promotions in Western countries (from what I know). It's basically unknown here in Europe.
