Had the inventors of the sun dial had a tablet, she or he would've made an app like this one.

The idea is to turn the solar system (shown from an Earth-centric point of view) into a working clock. According to the publisher, this app combines several types of mechanical solar systems from the past (search on terms like antikythera mechanism, orrery or armillary sphere) with the ability to speed up time. There's also a GPS function, so you can see where you are on the Earth as you spin. We liked that you can freely spin or zoom in/out on the globe, although some of the control panels are hidden and hard to find. The clock face is built in the ecliptic and around the planet earth.

Note that this is a "one trick pony" app that could be used by teachers to help students understand the relationship between time, clocks and the celestial dynamics.

I am Markus and I belong to developer team of the Cosmic Watch! I think for teachers it is interesting that the Cosmic Watch is actually the worlds first astronomical clock in the digital age. So it is a milestone in the history of time dispalying. Besides this monumental fact, it shows the connection between time and the celestial dynamics in the most stunning way ever. To understand time as the actual position in the solar system the Cosmic Watch really can awaken people on the issue of time. Time is no longer just a abstract number but our actual position in this grand stellar ballet we are all living in. TIME IS THE COSMIC RHYTHM. If teachers can brings this message accross to their students we - the developers - are very happy and we are sure it will have some implication on the appraoch to our most precious good we have - TIME on our EARTH.
