You must go to the provided coordinates and discover how to convert from the "local time." The coordinates won't bring you directly to the source. You still have to do some detective work, but what you seek is in the open. With this information the following will shed light on the cache location.
N 31° 57.ABC W 110° 58.DEF (puzzle coordinates = N 31° 57.401 W 110° 58.528)
A = puzzle_A + March 31
BC = puzzle_BC + January 15
DE = puzzle_DE + (2 x December 1) + November 15
F = puzzle_F
To check your solution "on the trail," apply the following checksum to the last 3 digits of the solution lat/long:
N 31° 57.ABC W 110° 58.DEF
27 = A + B + C + D + E + F
o While the area is open 24/7, the sundial is 100-ft from the police station, so searching at 3:00am may attract some unwanted attention.
o Remember, adding a negative is the same as subtracting a positive.
4 + (-2) = 4 - 2
o When in doubt, round to the nearest 5th
o Hard packed dirt
