I started the timer just now at 21:26pm which would run the script at 22:26, 23:26, 00:26 and so on?
If you started the timer at 21:26, it will start to run the second timer at 22:00, which is running every hours, note that at 22:00, the command associed with this second timer won't be executed, you have to execute it separatly when you run this second timer
