CLOCK0 Purpose
Use the CLOCK0 (zero) statement to disable or turn off the free running clock
resident on the BASIC module. After CLOCK0 is executed, the special function
operator TIME no longer increments. CLOCK0 is the only module statement that
can disable the free running clock. CLEAR and CLEARI do not disable the free
running clock, only its associated ONTIME interrupt.
Syntax

IMPORTANT
CLOCK1 and CLOCK0 are independent of the clock/calendar.
