I noticed today that a streak of my commits on a branch all thought they were made on the same day. I knew this wasn’t true, so I investigated.

First thought was that maybe git was using the time when my tmux session started. That was incorrect.

Then I remembered that my workflow on this branch was using git commit -c HEAD so I could reuse parts of my commit message. (I like to put a header with the ticket number and title on my work commits, in case we need to come back to the original ticket that justified a change.)

It made sense, then, that git was reusing the commit date as well. This is where I get really proud of myself: like a real adult, I used git commit -h and found out how to fix my issue without using the Internet.

Mindblowing stuff, I know.

Anyway, the fix is to add --reset-author, and git recognizes that your new commit is being made by you, right now.
