Why does a sundial show an earlier time than the official time?
The solar time must be corrected for the longitude of the sundial relative to the longitude of the official time zone. For example, an uncorrected sundial located west of Greenwich, England but within the same time-zone, shows an earlier time than the official time. It may show “11:45” at official noon, and will show “noon” after the official noon.
How does a portable sundial work and how does it work?
Portable dials are self-aligning: for example, it may have two dials that operate on different principles, such as a horizontal and analemmatic dial, mounted together on one plate. In these designs, their times agree only when the plate is aligned properly. Sundials may indicate the local solar time only.
Is there a way to correct hour lines on a sundial?
This is also a correction that can be done on the dial, i.e. by numbering the hour-lines with two sets of numbers, or even by swapping the numbering in some designs. More often this is simply ignored, or mentioned on the plaque with the other corrections, if there is one.
How are the different types of sundials different?
There are several different types of sundials. Some sundials use a shadow or the edge of a shadow while others use a line or spot of light to indicate the time. The shadow-casting object, known as a gnomon, may be a long thin rod or other object with a sharp tip or a straight edge. Sundials employ many types of gnomon.

What does it look like when you have flat poop?
A lot of times, your poop looks a lot like your intestines. It’s slightly rounded and lumpy. Flat poop isn’t round. Instead, it’s square or string-like in appearance.
