I am only commenting for the archive to confirm that those should be
good.  Here are references for those reading later and wish to check
for updated information.

And, with Debian 6 LTS, in /etc/apt/sources.list, I have, apart from
the commented out lines,

"
deb http://http.debian.net/debian/ squeeze main contrib non-free
deb-src http://http.debian.net/debian/ squeeze main contrib non-free

deb http://http.debian.net/debian squeeze-lts main contrib non-free

deb-src http://http.debian.net/debian squeeze-lts main contrib non-free

The tzdata package is updated through the stable-updates section, not
to be confused with the security stable/updates section.  They are
similarly named but different update channels.  The stable-updates
path is the one time named "volatile" section for those that remember
it.  It is for updates that by their nature must update more often
than the Debian Stable release and point release cycle.

Packages such as tzdata are updated when governments change the
timezones.  This happens outside of distribution release cycles.

For Debian Stable Jessie 8 the following shows all three sets of
sources that one should have in their sources.list in order to get all
of the updates they should be getting.[*] This is the main archive
where most packages exist, the updates source for packages such as
tzdata, and the security source for security upgrades.

deb http://httpredir.debian.org/debian jessie main
deb-src http://httpredir.debian.org/debian jessie main

deb http://httpredir.debian.org/debian jessie-updates main
deb-src http://httpredir.debian.org/debian jessie-updates main

deb http://security.debian.org/ jessie/updates main
deb-src http://security.debian.org/ jessie/updates main

Bob

[*] Note that httpredir.debian.org is the redirector and the same as
if one had the geographic alias ftp.XX.debian.org where XX is your
country code such as ftp.us.debian.org.  Either is okay.  I am using
the redirector in the documentation above so that it is generic.  If
you have the country code alias version that is fine too.

Hello.

Thank you for that, Iain.

Due to some of my web browsers not having the capability to save
sessions, and with them having multiple windows open, and with kernel
updates requiring a system reboot, each time, this system has not been
updated for a little while, so, upon checking (using Synaptic) the
tzdata package(s), and finding they needed updating, apparently
without depending on the kernel update(s), I have now updated the
tzdata packages. There are tzdata and tzdata-java, both of which had
updates available.

Good to see that Debian has already implemented the patches through
Debian Squeeze LTS.
To be fair, this was implemented when squeeze was still stable, as 
according to the below link Wheezy was officially released over 7 months 
after this fix

Nice one Bob. This link also points out this was an issue with the NTP 
server software (although it seemed in 2012 the main issue was with the 
kernel)



Bret

 You may want to also check your version of NTP (if you are running the 
software). You may also want to check your version of the tzdata package 
if you are *not* running NTP. This should be 2015d-0+deb6u1

Good to see that Debian has already implemented the patches through
Debian Squeeze LTS.

Hello.

I have posted this message to the general Debian Users list, rather
than to only the LTS list, as, whilst my interest is limited to Debian
6 LTS, I believe that, if the issue involving any possible problem,
applies, then it would likely apply to all existing versions of Debian
Linux in use.

I have today seen the news report below, and wonder whether it needs
some kind of patch for Debian Linux, and, if so, whether it has
already been done, or is pending.
