We can run queries against events like issue open/close, labeled, miletstoned etc. so we can generate reports with time analytics. If it is just card open to close time, we could definitely bump that up or list!

For us it's a combination of a timesheet (so we can get paid) and a run down of time spent (vs estimated) on specific tasks. Those are the two important bits.

EDIT: To clarify, since it's being used as a timesheet, we need a timer.

Thanks for the link! I think we'll have to add a new events table to track things like how long it takes to move from "Tasks" to "In Progress" to "In Review". It shouldn't be terribly challenging, and I love me some analytics.
