So, I was exploring LoML (It really needs a name), and by the Dongae Office in Nampo, it suddenly got dark, and it was 7ish AM in game, 5:30 PM Pacific Time, USA.  Stars everywhere, and it bugged me.  I switched characters to leave Loml, and see if it was a local issue..... it was still dark, at 8 AM.  So, I quit of the game, and logged back in.  Loaded a character in Calpheon and it was morning again.

Clearly I must not have been in the Land of the Morning Light, as it became dark as night.
