You will have to update /etc/localtime somehow if you have the old 
zoneinfo file.  /etc/localtime is not an alias to the zoneinfo files in 
/usr/share/zoneinfo/... so an update of the tzdata file will not 
automatically update /etc/localtime to the newer one.  It has to be 
copied from /usr/share/zoneinfo by default.

I suspect that there will be a bunch of systems that have the wrong time 
because they incorrectly might assume that the yum update of tzdata will 
update /etc/localtime.
