Is /etc/localtime a file rather than a symlink?  Some people copy the  
TZ file into etc, which means it doesn't get updated when /usr/share/ 
zoneinfo is changed.  Try:

   rm -f /etc/localtime
   ln -s /usr/share/zoneinfo/America/New_York /etc/localtime

...or choose whatever location is most appropriate.
