Solaris 2.7 Daylight saving time fix.

Hi,
   I am working on getting Solaris 2.7 compliant with the new DST changes for March 2007.  I downloaded the latest updates from:

wget ftp://elsie.nci.nih.gov/pub/tz*.tar.gz

Ran zic on northamerica
Then tested with a zdump:


zdump -v EST5EDT |grep 2007


which still reported April when the DST would occur.  What am I missing? this worked for linux.
