Syntax/Switch that will allow me to stop JKDefrag at 6AM

I need to find out what switches need to be installed in the defrag script, or what syntax will allow me to put in a stop time.

We are currently using the program JKDefrag, the batch command is started from Windows Scheduled Task, but I've had no success finding a syntax that will allow me to put in a stop time (6AM). The code is below.

"AT 4:00 /every:su,m,t,w,th,f,s "C:\Windows\JKDefrag.exe" -example-

Edit to suit your needs

Time Format is 24 hour Military time

AT 12:00 /every:su,m,t,w,th,f,s "C:\Windows\JKDefrag.exe" (IT)

AT 18:00 /every:su,m,t,w,th,f "C:\Windows\JKDefrag.exe" (Servers)"



Any help would be appreciated.
