showrev -p shows what patches are installed. But not when.I'm not aware of a way to do that.

When you install a patch or package for that matter, it write information to the disk. I should hope that it creates a directory and writes the current date and time to that directory before it writes the files to the disk. Checking the date and time stamp on the directories should yield that information.

Also you can look at the date with "pkginfo -l" command. From patchadd -p command look at the name of package, and from pkginfo -l command you can see installed date of package. .......zulusa

Maybe:ls -la /var/sadm/patch/*/logNote that if you are running an updated release (such as Solaris 10 01/06 or 06/06), not all patches will turn up in that list, since some are included in the OS installation. .7/M.
