If you make several commits over a long period of time, with no activity in between, it seems that the Recent Activity feed groups them all together under the date of the last commit. This is somewhat misleading.
In the attached image, I made a commit 7 minutes ago, following two other commits made 12 days before that. They are all grouped under the heading of "7 minutes ago"
Apologies if I put this in the wrong component group. Not sure where to put it.
