Dwaipayan, there are two ways:
- We build a bot listening to mailing lists and check. I like that
implementation idea for various other checks.
- Stephen Rothwell could include this as a check on linux-next and
inform the git author and committer.

I am wondering though if that is worth the effort, three instances of
a wrong date among 1M commits seems to be very seldom and the harm of
that mistake is quite small as well.
