Most assuredly not the right way to look at it.

And of course date of the commit has nothing to do with anything either.

Think about the branched development model. Let's say I do some work, basing
my
work on, say, 2.6.0. I spend a lot of time on it. Then I send a pull request to
Linus (or whoever). He merges it. When looking at my commits, you might think
that you're looking at a 2.6.0 kernel, based on the Makefile. And in a large
sense you are. But in reality the commits were merged into some much later
release. Same with dates.

You can either read about git and fully understand it, or you can kinda trust
that the tools aren't lying to you when you ask for a bisect in a range, or
a
log of commits between two revisions.
