If it's already shared history it would be too late anyway - thread is about lying when you authored/committed.

Not really sure what the benefit in cheating your boss would be though? You still had to do the work at some time. Maybe you work extra hard one day but push only the first half of your commits, then give yourself a day off where all you do is check in at the end to push the fake-timed other half of them?

It'd probably be easier to find an 'unlimited holiday' job that pays you for output rather than keeping your seat warm.
