TimedExecute restart

I just started a server again, and I used TimedExecute to restart my server before but I forget how I did it I tried "4:06:00": "restart 120", and  "4:06:00": "sr.restart 120",   but nither of them are working. how do I write it out ?

"EnableRealTime-Timer": true,

"RealTime-Timer": {
"09:00:00": "restart 120"

Thank you.
