   Not art all, since we are dealing with time as shown on the clock. Even   
   when daylight savings time isn't in force, noon on the clock rarely   
   precisely corresponds to when the sun is due south. And of course if you   
   went by "sun time", places on different longitudes that are currently   
   within the same time zone would be setting their clocks to different   
   times, as happened prior to the middle of the 19th century.
