Hello.
My team get some trouble when they are working with issues, which have been opened long time ago.
The usual "date" concept here is calculate how long time ago the issue was updated or created and then round that time to:
- days (before week ago, without round)
- weeks (before month ago)
- month (before years ago)
- years ago.
It'll be good to have ability to see the exact issues creation or update date.
