How to find the age of open ticket based on the working calander ( Exclude non working hours and holiday)

[Prem Prakash gautam]

Hi,

We do have options like exporting Response Time, Resolve Time, On-Hold time but I don't see an option to get open time, How do I get it. 

I know that we have a time when the ticket was logged but if I calculate from that, it will give me the age including non working hours and holidays which I don't want.

I've moved this to the Reporting section - I'm not sure that the ITOM team would be over-excited about replying.
