//Funktionen MainWindow

  // Get a tm structure
  time_t temp = time(NULL); 
  struct tm *tick_time = localtime(&temp);

  int hour = tick_time->tm_hour;
  int i_corr = 0;
  
  if (hour > 12){

  }
 
  // Get image center
  GRect img_bounds = gbitmap_get_bounds(s_background_bitmap);
  GPoint src_ic = grect_center_point(&img_bounds);

  // Get context center
  GRect ctx_bounds = layer_get_bounds(layer);
  GPoint ctx_ic = grect_center_point(&ctx_bounds);
  
  // Angle of rotation
  int angle = ((hour * TRIG_MAX_ANGLE) / 12) + i_corr ;

  // Draw!
