So, basically the server says "America" however, for most of SOUTH AMERICA (part of america for the ones that says that america is only EEUU): 

Server Time: 12.00 Pm, World boss.
Most of SouthAmerica: 17.00, World boss. Until here? no problem at all.

But lets check the other times.

Server Time: 20.00, World Boss.

Most of SouthAmerica: 01.00 AM.

Node Wars: 19.00 & 21.00

Most of SouthAmerica: 00.00 Am & 02.00 AM.

For us in SouthAmerica, server times are just ... unachivable most of the time.
