A caveat of only updating tzdata is there but there is no built in mechanism to update /etc/localtime to the latest timezone unless the system is already running glibc-common version 2.3.2-95.40 or greater. If the system is not on these versions, there are additional options. Any of these can be used to update the localtime information:
Update both glibc-common and tzdata at the same time in the same up2date run or with the rpm command. This will lay down a new binary from glibc-common called tzdata-update which resides in /usr/sbin. The tzdata package is a requirement of glibc-common, so it will be installed first and will lay down the new tzdata files...
