utes, seconds; SUN(0) = Sunday.
• The CPU Unit's internal clock will start when the following Clock Read/
Change operation is executed, when the time is read/changed from
another Peripheral Device, when a FINS command is used to read/
change the time, or when the DATE instruction is executed from the user
program.
• The time data for the CPU Unit's internal clock is stored in the Calendar/
Clock Area (A351 to 354) in the Auxiliary Area.
