Even more functions for the Arduino GPS Clock

The multi-face Arduino GPS Clock has some new clock faces in software
version 1.3.0:
Demo mode, where all screens are cycled through, with 10-15 seconds per screenAstronomical clockWordclock displayRoman numbersMorse code clockThis brings the total to 35 different screens. The updated code as well as documentation is on my Github page.
The astronomical clock shows sidereal time as well as solar time:A sideral
year is one day shorter than a solar year, as noon is defined when the
earth points in a particular direction relative to the stars rather than to
the sun. Further explanation is here: sidereal timeApparent solar time has
noon when the sun is exactly to the South. It takes into account the shift
due to daylight saving time, the shift due to my longitude relative to the
15 degree zone per hour, as well as irregularities in the Earth's orbit
around the sun. See solar time here.
