Another solution might be to ask the git developers if they would be
willing to have "git am" print a warning if the date is sufficiently
insane (say, more than 3 months in the past or present).

One could also imagine a request that "git log" would have a new
format where normally the author time is printed, but if it's
sufficiently different from the commit time, the commit time is also
printed in parenthesis.

Or you could set up your git config so that "git log" uses
--pretty=fuller by default, which prints both the author date and
commit date.

Like Lukas, I'm not really sure it's worth the effort, however.
