forget what time it is when the power is turned off in a power outage. The
second solution is to
simulate a Real Time Clock in ScriptOS. This solution
does have the advantage of being free , but has the disadvantage of being off by
approximately 1 minute per day and forgetting what time it is if the power goes
out. If a standard UPS is used, and some device (or person) resets the time once
per day, these problems can become negligible.
Both solutions write the hour, minute, second, and frame to four state variables.
I will now show you several examples of using the Real Time Clock (either
external or simulated).
Start Event at 8 p.m.
This sequence is started whenever the HourVar reaches 20.

Start Event at 11:58 p.m.
This sequence is started whenever the MinuteVar state variable reaches 58
minutes, and then checks to see if
HourVar
is 23. If it is, it starts the event, if
not, it exits.

Start Event Every Hour.
This sequence is started whenever the
HourVar
state variable changes.
Because sequences always look for edge-triggered occurrences, every time
HourVar is changed, this sequence will run because HourVar will always be
greater or equal to zero.

Start Event Three Frames after Every Minute
from Midnight to Six a.m.
This sequence is a little hairier, but is again demonstrative of the power of
ScriptOS.
