We already know which kingdoms are which from the previous episode,

Weiss plays Vacuo in the North,

Ruby plays Atlas (possibly Mantle and Atlas is the city) in the East,

Blake, Vale in the South,

Which leaves Yang with the West.

This means Vale and Atlas Do not share the same timezone, and it's Vacuo and Vale which have the similar times
