This extension changes relative time displays like 3 days ago, 20 minutes ago etc. to display the actual full date
and time.
Why?
The advantage of this, is say you are viewing a page of GitHub project commits or releases for example. All thes dates show up as 3 days ago, since they are all off by a few minutes or hours. It can be extremely frustrating to have to hover over each of them to find out the exact time of each release.
