A sundial only tells the right time where it was designed for. This one is calculated for San Francisco: the hour lines are laid out for 37.77 degrees north, and the gnomon stands at exactly that angle, so on a sunny day the shadow lands on the right hour.
MADE FOR SAN FRANCISCO
Because San Francisco sits 10 minutes of sun time west of its time zone's meridian, the hour lines are shifted to match, so solar noon falls where it should on your clock. It reads standard time; during daylight saving time add one hour.
SET-UP
1. Mount it level on a post, wall cap or pedestal (3 countersunk screw holes).
2. Turn it so the gnomon points to true north (not magnetic north: use a map, a phone map app or the North Star).
3. That is it: no batteries, no wiring.
ACCURACY
A sundial follows the real sun, which runs up to about 16 minutes ahead of or behind the clock over the year (the equation of time). It is spot on around mid-April, mid-June, September 1 and Christmas.
