Setting the clock
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. Astronomical data for many
cities in the world is given in Appendix F Time and location, page 369. 13
