Using system to run scheduled jobs - PowerShell

Hello everyone,

I have a question related to this thread:

http://social.technet.microsoft.com/Forums/en-US/winserverpowershell/thread/9142d89d-2958-47a9-9dec-03abf0536a12

The question is does anyone know how to use the Powershell scheduled jobs cmdlets to have the NT Authority\System account run a ScheduledJob?  I've thought about it a couple times but I haven't seen how to do it. 

Thank you in advance for all your help!

Hope that helps! Jason
