[time-nuts] Local Solar Time Clock

[Chris Albertson]

ll the solutions proposed so far don' meet the criterion that the clock not
be software.   It's too esy to make a software display.  yu just start with
UTC and apply a formula from an amanac.

But what was requested was something made with gears and springs

I wonder if you really need a special clock?  Can't you adjust a normal
spring driven clock to run fast (or is it slow?) by about 1/3 of a percent
(one day per year)?  This should be within the range of adjustment.

So take a normal clock and go outdoors at noon and look at your sundial.
 Set the clock to 12:00 at local noon.   Then the next day check again and
adjust the lever on the rear of the clock to make it go faster or slower.
After a few days it should work.
