Hi.

I use CentOS 5.4, the free version of RedHat. I looked in /var/log, and found some logs for "yum". Here is a script that shows a sample of when some updates were made:
Code:
#!/usr/bin/env bash

# @(#) s1	Demonstrate time of update.

echo
echo "(Versions displayed with local utility \"version\")"
version >/dev/null 2>&1 && version =o $(_eat $0 $1) 
set -o nounset
echo


ls -l /var/log/yum*

echo
head -3 /var/log/yum.log

exit 0

producing:
Code:
$ ./s1

(Versions displayed with local utility "version")
OS, ker|rel, machine: Linux, 2.6.18-164.11.1.el5, i686
Distribution        : CentOS release 5.4 (Final)
GNU bash 3.2.25

-rw-r--r-- 1 root root  3308 Feb  5 12:00 /var/log/yum.log
-rw-r--r-- 1 root root 43464 Dec 23 18:33 /var/log/yum.log.1
-rw-r--r-- 1 root root 38360 Jan  2  2009 /var/log/yum.log.2

Feb 05 11:50:24 Updated: selinux-policy-2.4.6-255.el5_4.4.noarch
Feb 05 11:50:31 Updated: kernel-headers-2.6.18-164.11.1.el5.i386
Feb 05 11:50:50 Updated: tzdata-2009u-1.el5.noarch

I have no idea if this is always the case for an update. The files may contain more than one set of updates, so you may need to process to collect the unique dates.

Best wishes ... cheers, drl

debuginfo-install

debuginfo-install(1)													      debuginfo-install(1)

NAME

       debuginfo-install - install debuginfo packages and their dependencies

SYNOPSIS

       debuginfo-install package

DESCRIPTION

       debuginfo-install  is a program which installs the RPMs needed to debug the specified package.  The package argument can be a wildcard, but
       will only match installed packages.  debuginfo-install will then enable any debuginfo repositories, and install the relevant debuginfo rpm.

EXAMPLES

       Download and install all the RPMs needed to debug the kernel RPM:
	      debuginfo-install kernel

WARNING MESSAGES

       Could not find debuginfo for:
	      You may sometimes see warning messages about certain packages not being found if you run debuginfo-install for a wildcard  or  glob.
	      Debuginfo  packages are not necessary for "noarch" RPMs; these will generate a warning message.  Additionally, On 64-bit systems, no
	      multilib debuginfo packages are published, so if you have 32-bit packages installed, these will also generate warning messages.

FILES

       As debuginfo-install uses YUM libraries for retrieving all the information, it relies on YUM configuration  for	its  default  values  like
       which repositories to use. Consult YUM documentation for details:

       /etc/yum.conf
       /etc/yum/repos.d/
       /var/cache/yum/

SEE ALSO

       yum.conf (5)
       http://yum-utils.baseurl.org/
       http://yum.baseurl.org/

AUTHORS

       See the Authors file included with this program.

BUGS

       There  are  of  course no bugs, but should you find any, you should first consult the FAQ section on http://yum.baseurl.org/wiki/Faq and if
       unsuccessful in finding a resolution contact the mailing list: yum-devel@lists.baseurl.org.  To file a bug  use	http://bugzilla.redhat.com
       for Fedora/RHEL/Centos related bugs and http://yum.baseurl.org/report for all other bugs.
