Hello,

In addition to “PowerShell: Run command at certain date/time”, we got the request to include a start time also.
In the script below, we are doing such thing. (write-host commands are in Dutch tho). 
In case the user specifies a valid start date/time, the script will start the program. (example program).
If the user specifies a valid date/time, the script will kill that program.  This script was made for DuvelRadio.
