Solaris 11 Package History

The pkg operations install, update, list, search, etc are well known.
Another excellent feature is the history. Using history you can
take a look back and see what happened on your image.

When did we update our Solaris System?

-bash-4.1$ pkg history |grep " update " | grep Succeeded
