The AstroClock that is viewed within KeplerWorkshop has been improved. You can now resize the AstroClock and step forward and backward in time manually by clicking on the arrow buttons.
Note that there are two AstroClocks in Sirius: there is one in Kepler Workshop and one in the main Sirius program. Both AstroClocks are similar but there are some features that are different in each program. One good reason for having the AstroClock in both the main Sirius program and Kepler Workshop is that you may be working on some particular part of one of themodules and do not wish to overlay the AstroClock over what you are doing or exit the section of the program you are in.
