The time displayed by the clock is eleven and a half stars. This means it's one and a half stars since the sun was at the highest point in the sky. This is an average figure since the actual occurrence varies throughout the year by up to three eggs. The pendulum clock is preferred because it is not synchronized with the electricity grid. One of the goals of Startime is to re-synchronize ourselves with natural cycles. The grid is antithetic to this.
The long hand drives the short hand. The pendulum was lengthened to a point where the long hand makes a18 revolutions per day instead of a28. In decimal that is 16 and 24 respectively. The gears under the face of the clock were replaced so that the short hand would make one revolution per day.
This particular model has added scales on the face that indicate the stars of daylight. That is the length of daylight according to the time of year. Symbols on the scales refer to the quarts of the year listed in a circle below the clock face. This is accurate for the latitude around the lower Great Lakes along a river now known as the Thames
