Would you do me a favor and show the output of zdump for this year for
your timezone?  Here is an example for my timezone of US/Mountain.

  $ zdump -v US/Mountain | grep 2007
  US/Mountain  Sun Mar 11 08:59:59 2007 UTC = Sun Mar 11 01:59:59 2007 MST 
isdst=0 gmtoff=-25200
  US/Mountain  Sun Mar 11 09:00:00 2007 UTC = Sun Mar 11 03:00:00 2007 MDT 
isdst=1 gmtoff=-21600
  US/Mountain  Sun Nov  4 07:59:59 2007 UTC = Sun Nov  4 01:59:59 2007 MDT 
isdst=1 gmtoff=-21600
  US/Mountain  Sun Nov  4 08:00:00 2007 UTC = Sun Nov  4 01:00:00 2007 MST 
isdst=0 gmtoff=-25200

What is the output for your timezone?  I believe this will be useful
information in understanding what is happening.

Please remember to keep the bug-coreutils mailing list in the To: or
Cc: list so that all may participate in the discussion.
