PIZZAQ! What time is it REALLY on this uncorrected sundial hundreds of miles north of its designed latitude / You can do this, you're smart / CONVERSELY: If you can't do this, you're not smart.

I received this sundial as a gift years ago, and I've lost the details, but I think it's a reproduction of a sundial designed by Thomas Jefferson for his garden at his estate of Monticello, Virginia.

Monticello is at Latitude 38° 0′ 37.01″ N

My reproduction is at  42° 23′ 30″ N

Sundials are latitude-specific, so if Jefferson did his trigonometry right (and he almost certainly did), this sundial only tells the correct time at Monticello's latitude.

Moving the same sundial substantially north or south will skew or distort the sundial's time-telling accuracy.

However, you can adjust for this by doing some more trigonometry and skewing the sundial's circular base up or down from its intended position parallel to the ground. If you get the off-parallel angle just right, the shadow cast by the gnomon will again tell the correct time.

I haven't skewed this sundial to correct for its new latitude, so, like Jefferson's at Monticello, it's parallel to the ground.

So what time is it REALLY?
