    Hello:
     
    Isn’t this the traditional “time sight” that one can use or do  from any  known location.  This is best done when the sun is well away from noon..... described as “ to the east or west”.  With a little practice and interpolation/averaging  I think you can achieve a time check to within 30 seconds,,,,,,maybe even 10-15 seconds. Someone  will let us  know achievable time accuracy.
     
    Best regards to all.
    Bruce
