a way to see the exact dates in place of the relative ones (BB-7428)

Looking at the code in a repo, I can't tell when a commit was made.

Use-case: We have contractors working on our code and when matching invoices for code done, we check the date of the work and the commits which were made.

The relative dates makes this difficult, and it's not possible to do in any good way (I was told I can hover over the relative date to get the actual date, but I think it should be possible to toggle instead).

For now, I end up using the console tool 'tig' to do this instead. It has the ability to do both relative and actual date.
