And some maintainers may choose *not* to act on a patch first, even if
they see it first.  They might be focused on bug fix patches, and not
act on cleanup or feature patches until -rc3 or rc4.  Or maybe they
will use separate branches for "urgent_for_linus" patches, so two
different patchs may end up in completely different git flows.

If you're worried about which one of several versions of a patch will
be applied, change the subject to [PATCH v2] ..... instead of [PATCH]
.... for the second version.

*Please* do this.  In fact, this is the one thing I wish git
send-email would do automatically, along with having a place to edit
and track the 0/N summary patch.

To be honest, I've only ever used that timestamp for reporting
purposes at work, and I'd be surprised if anyone was doing anything
other than that with them.

Thanks for your detailed feedback.

Note also that some maintainers have work flow that deliberately smash
the date (i.e., because they are using a system such as guilt), so if
you are depending on the submitted timestamp, it's going to break on
you.
