I have a scheduled apex job which updates a field which is controlled by a validation rule as follows:

    AND(
    	Not(ISNEW()), 
    	$Profile.Name != "System Administrator",
    	ISCHANGED(theFieldInQuestion)
    )

This validation rule prevents anyone from changing the value in theFieldInQuestion UNLESS that person is a System Administrator. 

The scheduler runs as system, according to the documentation located here:

My question is : What can I add to this AND clause in the validation rule which would allow the Scheduled Apex Job to update theFieldInQuestion ?
