Not hardly.  I tried already.  The existing timestamp_mi behavior is
probably as close to 8.0 as we can get given the change in underlying
representation.

[ shrug... ]  We've changed datetime behavior in every past release,
we're changing it for 8.1, we'll probably change it some more for 8.2,
and again after that.  All the datetime code is a work in progress.
Get used to it.
