The time that subversion stores for the *revision* will be 3/2/2007.
It is my understanding that subversion relies on the fact that the
'svn:date' property is never decreasing as revision-numbers increase.
(disclaimer: Note that I may be wrong about that...)

Certainly subversion expects the 'svn:date' property will have the exact
same value for all files which are checked-in in a single 'svn:commit'
command. I'm pretty sure you cannot avoid that fact. This is why it
is so significant that the 'svn:date' is a property of the *revision*,
and not a property of each file which was changed in that revision.

Another possible solution is to add some new property, and let svn
continue to use the 'svn:date' property in whatever way it wants to.
Perhaps svn itself would keep track of this new property. If not,
then you've got to make sure to add the appropriate hooks to make
sure this property is updated at commit, and handled appropriately
at checkout/update time. It's a little work, but it certainly should
be doable.

One of the really nice things about subversion is that you can add
whatever properties you want to add, to track whatever meta-data you
want to track.

I am not familiar with this tactic for messages in a mailing-list. I'm
don't understand how it could work reliably in practice, but I've added
my address to the 'Cc:' of this here reply! :-)
