Sundials need to compensate for the equation of time to show mean solar time, and for precision sundials this often means they have a sliding part that is adjusted daily. I am amused by the idea of a sundial with a DUT1 setting...

DST is a pretty neat way of using the timezone system to get away from noon-oriented time and closer to a sunrise-oriented timetable. The latter is much nicer psychologically but damn awkward for timekeeping.
