Description of problem:

When selecting to sort the RPM package list for a system, the installation dates are processed alphabetically. It would be expected for the sort order bo be chronological.
 
Version-Release number of selected component (if applicable):

5.4.1

How reproducible:

Always.

Steps to Reproduce:
1. Select a system.
2. Select "Software"
3. Select "Packages"
4. Select "List/Remove"
5. Select "Installed"

Actual results:

Installation dates are sorted alphabetically (either ascending or decending).


Expected results:

Installation order should be presented chronologically.


Workaround:

On the client, use "rpm -qa --queryformat" to display the date, then post-process that to convert the unix timestamp to a user-preferred format.

rpm -qa --queryformat "%{INSTALLTIME} %{NAME}\n"  | sort -n | awk '{print strftime("%Y-%m-%dT%H:%M:%S",$1),$2;}'
