Calculate how long a ticket has been assigned to someone?

Is there a way to calculate how long a ticket has been assigned to someone?  Ideally seeing how long it was snoozed by them, in progress, on hold, etc?   We find that a lot of inefficiency comes from the ticket sitting with the wrong person for a long time.  We would like to surface this and encourage tickets to be re-assigned to the right person who can take action.
