The timezone data gets updated pretty regularly. (I think there were 16 or so changes to the upstream package last year.) Remember the US isn't the only country that passes laws that affect local time, so that one would expect few of these changes to matter to you if you only care about local time in one location. If you dual boot with Windows you might have issues. Normally you want your hardware clock set to UTC, but Windows users typically set it to localtime instead. The problem with this is that you need to adjust the hardware clock and with more than one OS needing to do this it might get changed more than once.
