Hi @Italo 
Welcome to the community!
Also if you need calculating the time between Item statuses i recommend you to try Time in Status app which helps to track time the Item has spent in each workflow status easily. So you can monitor how fast the Item moves between statuses.
You’ll get user-friendly data on the board in a few seconds.
Also you will be able to track how much time your issue spends in each status and much more by generating:
And use charts to visualize your reports a sample of a certain number according to time range/item range, or a single item:
- Pie Charts
- Bar Charts
- Area Charts
The app is also available in the format of board integration.
Start the 14-days free trial to try it out for yourself and share your experience with us.
Hope you find this app helpful,
Valeriia
