You have then two different pointers to the same timezone?

How about adding a comment:
// Note the KTimeZone pointerr becomes invalid when you call reload


Btw. how many timeszones are there anyhow?

Note that this may add other headaches like a pointer ending in two
shared pointers and the KTimeZone unaware of its own shared_ptr.
