Happy Hour again

Is there any other alternatives to set the happy hour price by not using the price list tag and the trigger?

Sometimes, the machine was powered up by that time or the app was not running by the start of the HH time. Then no trigger was launched.

I am looking for a script (or a rule conditions) to return a value if the current order time is between xx and yy for example. Then from there we can do price calculation.

@neko SambaPOS should execute missed triggers when started.
