Also, this assumes that the original commits weren't fudged to begin
with, before pushing to Github.  After all, git *does* let you override
the date(s) stored in each commit.  And one could set the hardware clock
to a different time, etc..

So it's not a 100% guarantee by any means, but there's a sliding scale
of increasing unlikelihood that, past a certain point, would just have
to be taken on faith barring circumstantial evidence that indicate
otherwise.
