Track the aging of a Case

I am fairly new to SuiteCRM (which is Great!). I would like to have the ability to track the aging of a case. Another words the length of time from when the case was created to now or when the Case is Closed. For example: 1 day 2 hours 56 minutes or DD:HH:MM.

Any help would be appreciated.

You would have to develop custom code to calculate the time between the date created and NOW. You could then store that on a field that you could create in studio, or manually in the code, so you can view the time the case has been open until closed.
