Random raid timer

Hellow im trying to use this config, i put 100% chance to raid but is not working, its been an hour since last raid, but nothing happen, i put a delay of 1200 sec and 900 sec authorized tc, but it pass an hour and not working with 100 chance to happen, what i need to do? this config is only for an event, i hope you can help me, thanks, i let you my config here in an image.

My bad there say minutes where i put 900 and 1200 is seconds because there is no minutes, im okay? where no minutes is write it will be seconds

Did you get it working?   900 = 15 hours

Yes it works, thank you
