SETTIME

Set System/Task Time of Day

This directive sets the TIM system variable for this task to a specific hour and decimal hour value based on a 24-hour clock.

SETTIME numeric-value

numeric-value is any number in the range of 0 to 23.999999…

This directive is used to set a value for TIM that is independent of the system value.

The value of the TIM variable is updated by the system based on the system clock (not less than once per second nor more than about ten times per second, depending on the operating system environment).

The value for the time is set on a 24-hour day schedule and in the decimal PRECISION 6 form of HH.hhhhhh [i.e., time runs from 00.000000 (midnight) to 23.999999 (11:59:59.9964 PM)].

SETTIME 8.5

assigns the variable TIM, the value 8.5000, representing 8:30 AM.

SETTIME X

if X = 20.5, TIM is set to indicate 8:30 PM.
