Gnomon Knows

Sundial at Thatcher Park

“Does anybody really know what time it is?” The title of a 1970 song seems to be literally answered by a sundial at Thatcher Park in Forest Grove, Oregon. Simply stand on the square that has the current month written on it and your body becomes the gnomon that casts the time-telling shadow. Just note where the shadow of the top of the head rests in relation to the hour markers of the dial. It seems easy enough, unless the sun is hidden by a cloud as it was moments before this photo was taken.

Fortunately the sunshine returned with enough glow to reveal the shadow pointing to about 12:15 PM. However, the clock on the cellphone said it was around 1:15 PM. I was momentarily confused until it dawned on me that the sundial showed the true sun time, or standard time, while the phone showed what I think of as “messing with daylight” time. Isn’t it amazing how easy it is to make simple things confusing?
