I can’t help much because I don’t have Alarm Pipelines installed on the machine I’m working on at the moment. A couple of tips though: You are mixing 24 hour and AM/PM. If you do that in your project you will have quite a bit of grief. I recommend 01:00 to 00:00 or 23:59:59. Also, punctuate and capitalise properly for ease of reading. You haven’t really explained where you are stuck. Make it easy for your readers!
