Comment 3 for bug 1349528

As already said in the review (https://review.openstack.org/#/c/124856/), this is something that should be fixed in radosgw, not as a workaround in python-swiftclient. IMO the list result should include the x-timestamp value, otherwise there is a difference to the Swift API and this should not be handled on the client side.

Apart from that iterating over all the objects just to get the latest timestamp might be okay if you only have a few objects, but not if there are tens of thousands or even more objects.
