Re: bug report: dates on diff

Imagine this scenario:

 - Contributor A writes a change on 2017-07-01 and send it in to me
 - Contributor B writes a change on 2017-07-03 and send it in to me
 - I apply change from B on 2017-07-04 on 'master'
 - I apply change from A on 2017-07-05 on 'master'
 - You clone the resulting repository from me on 2017-07-06

Now, you have at the tip of 'master' in your repository the commit
that records the change by contributor A.

And there are three times that are relevant to your tip of 'master'.

 - When was the commit that sits at the tip of 'master' made?
 - When was the change recorded in that commit made?
 - When was the commit made at the tip of _your_ 'master'?

and the answers are 2017-07-01, 2017-07-05 and 2017-07-06, respectively.
They are called "committer", "author" and "reflog" timestamps.

Oops, obviously the dates have to be 2017-07-05, 2017-07-01 and
2017-07-06.  I made the commit on the 5th (i.e. "committer"
timestamp) that records a change written on the 1st (i.e. "author"
timestamp).
