Clock settings in Express consoles

The console clock is called a real time clock because it is set with respect to the true time for your location, not a relative time such as would exist for a time code signal.

The console’s real time clock also functions as an astronomical clock, which means that you can set it for the latitude, longitude and time zone at your location and thereby control real time programs with respect to sunrise or sunset.
