Any reason why none of our patches show up with an installed date after
August of 2008 (I think that's when I had last updated the ZAM server,
but two weeks ago I applied the latest patch and PRU for ZAM 7.5)

However, on all the machines, when I look at Hotfixes, I see a bunch of
KB patches that have no installed date, even though I know they have
been installed in the last 3 weeks.
