   Due to the inclination of the Moon's orbit relative to the Earth's equator,   
   if one were at a latitude of more than 62 degrees (e.g., parts of   
   Scandanavia, the Baltic states, Russia, and other northern countries),   
   it is possible the Moon may not rise above the local horizon at all   
   at certain times of the year.

   ...There is also a technically involving the question of "same time."   
   South Africa uses the time-zone for Eastern Europe, even though much   
   of it is as far west as Western Europe --- so at a given longitude,   
   moonrise in much of South Africa will be an hour later _BY THE CLOCK_   
   than it would be at that longitude in the middle of Europe...
