Other than looking at the dates when pkgs were applied in /var/log/yum.log* how can I tell when the last time a RedHat system was patched? My systems don't have regular access to the web.
Thanks in advance.

One other thing I need is the installation date of the system.
I found rpm -qi basesystem for the install date. Is that the best option?
