Does the "gitgitgadget" thing lie on the Date: e-mail header?

Postdating the patch with in-body header is fine, but mailbox tools often use and trust the Date: timestamp when sorting and finding messages etc. so sending a new patch to add linear-assignment.c that is different from what was added 9 weeks ago with "Date: Mon, 30 Apr 2018" header can easily cause me to miss that message when I look for things that happened within the past few weeks, for example.
