sundial

A sundial app for the iPhone, the semi-useful side effect of which would be a true solar time and local mean time display.

So applied to the sundial, this means there exists some shape such that its shadow at some time of day will be that time.

A tall sundial would not have enough mechanical stability to be accurate, especially due to wind loading.

A (decent) watch does not attempt to replicate the inadequacy of a sundial; it just tells you the time.

On a wall-mounted sundial, the shadow moves counter-clockwise (in the Northern hemisphere, the hemisphere referred to throughout this article).

Yes, the idea of mapping the horizontal sundial to a vertically-oriented image in our minds seems to hold a certain sense...

In the context of a sundial (Edit: in the northern hemisphere), it makes more sense.

Confound him, too, who in this place set up a sundial, to cut and hack my days so wretchedly into small portions!

As long as you're at a fixed location, how about a sundial?

I always wondered if it was possible to make a sundial with a minutes pointer...

When I was a boy, my belly was my sundial — one surer, truer, and more exact than any of them.

Maybe using a sundial the height of the Eiffel Tower?

As for the "simulacrum" comment, don't forget that watches are just a mechanical simulation of a sundial.

I think "sundial" alone is probably enough for most people to understand.
