Hello. I am using Yet another Software Tool 2 (YaST2) in an openSUSE-12.1, Linux operating system. I want to see a list of all of the openSUSE-12.1 updates I installed on a certain date. How may I see such a list of update names and dates of their installations, preferably one I can have sorted according to the date of installation? I didn't see a column for the date of installation of software packages on YaST2's "Installation Summary" tab.
