TPlannerAlarm, the alarm message is not shown

Hello, I'm currently using TDBPlanner v2.5.13.0, and I have my own editor where I set up tue alarm, using as Handler the TalarmMessage.

If I create the Item at the time where the alarm should be activated, inmediatly it runs well, but if I create this Item at an earlier time, and wait, the alarm message is not shown.

Is there any tip to make alarms being watched, on a certain time range?

Thank you very much indeed.

Did you have a look at this sample:
