The tools that exist will let you track things like "when the ticket was opened" to "when it was responded to" - but not things like how long your support agents spend looking after your customers. (Assuming that's what you're after.)
Tickets (in my opinion) are missing a "per activity" timer function. (A manual entry field would help!). I've implemented an "Accumulated time" manual property field for every ticket - but that has limitations if you want to report on all the time your agents spent on supporting customers in a particular time period.
The only option I have found so far is external app integrations like Toggl integrated with tools like Zapier - both applications are separately chargeable - so it gets expensive quickly.
