With the clock function, clock data in the C Controller module are read out by the user
program to be used for time control.
These clock data are mainly used for time control of the C Controller module system,
such as storing time and date information in the event history.
Even while the C Controller module is powered off, reset or has failed for longer than
the allowable momentary power failure time, the clock operation continues by the
battery inside the C Controller module.
The following clock data are used in the C Controller module.
