      It is, but the times of sunrise and sunset are not symmetric about
      midnight, not even if you don't have daylight savings time, and not
      even if you have the same longitude as is used nominally to define
      your time zone. Thus the times of latest sunset and of earliest
      sunrise are displaced a few days from the summer solstice, and
      similarly for the winter solstice.
      
      If you have a globe or map old enough to show an analemma, or if
      you remember any of the _Sky_&_Tel_ articles that describe efforts
      to photograph one, then you are on the starting point to figuring
      out a little more detail of what is going on.
