It turned out that the second patch required a bunch of other patches and 
those required still more.  Altogether it was asking for about a dozen 
patches and some had special instructions.  I'm not sure that all of them 
were free and at least one was listed as "obsolete" but without a newer 
patch to replace it!  I didn't really want to get into all of that.  They 
weren't security patches.

So I installed patch 109809-06 "timezone data patch" which had no 
requirements and it seemed to fix the time immediately, even before 
rebooting, but it had these notes:

NOTE 1:  Reboot system after patch installation.

NOTE 2:  To comply with the "U.S. Energy Policy Act of 2005" which will
          change daylight saving time transition dates beginning in 2007
          (see bugid 6348147), please also install the following patch:

          108993-52 (or greater)  LDAP2 client, libc, libthread and
                                  libnsl libraries patch

So I rebooted, because they told me to, but I didn't install the patch 
from Note 2 because that one (actually revised to 108993-66) was the one 
that required the other dozen patches and might not have worked out. 
Maybe I'm not fully compliant, but if I have the right time, that's 
probably compliant enough for me!

The patch added files in /usr/share/lib/zoneinfo, and for me this file was 
probably most important:

/usr/share/lib/zoneinfo/US/Central

It's a binary file.  I think they should consider using text files with a 
series of rules for the timezone instead of using a binary file to encode 
all that.  Anyway, maybe they have good reasons.  So, /etc/default/init 
was not changed, which makes sense because I'm in the same timezone, just 
using different DST rules.
