Yes. Mailman does it too for 'anonymous' lists, even though strictly
speaking, I don't think it's compliant.

If you did decide to change the Date: header, I don't think there would
be any repercussions, at least on an announce list with locally
submitted posts.

I think there could be an issue on a moderated discussion list if
someone were to claim that her post was sent before certain other
information was available, but you munged the date, but it doesn't
seem likely.

If I were going to mung the Date: header, I would probably put the
original in an X-Original-Date: or similar header.
