How would they even do it?  They will keep seeing two different zones
that happen to have the same content (and are actually hard-links of
each other).

The user will still see either "CA: Eastern Standard Time - Atikokan,
Ontario and Southampton I, Nunavut", or "PA", depending on whether their
zone is set to America/Atikokan, or America/Panama.
