When and how can I use the "Hours since.." in the Supervisor rule?

The "Hours since.." parameter indicates the time taken since an event has occurred in hours. You could set up a Supervisor rule using any the below "Hours since.." condition and automatically execute the required action : 

• Hours since created 
• Hours since pending 
• Hours since resolved 
• Hours since closed 
• Hours since reopened 
• Hours since first assigned 
• Hours since assigned 
• Hours since requester responded 
• Hours since agent responded 
• Hours since First Response Due 
• Hours since Overdue

For example, if you would like to close a ticket automatically after the ticket is in 'x' number of hours in pending status or if you would like to send an email to a particular agent when a ticket is overdue or is not responded for a while you could make use of the "Hours Since.." condition in a supervisor rule.
