Currently by default, a tzselect user who chooses Vietnam is given two 
choices, and can pick either zone appropriate for Vietnam since 1970. 
Unfortunately tzselect will have glitches if an installer uses 
non-default installation options such as PACKRATDATA but fixing that 
would take more work than I expect any of us can spare.

I haven't documented tzselect's -t option, since it can be glitchy. But 
if it's documented as being glitchy/experimental/whatever I suppose that 
would be OK. Any such documentation should be in both the man page and 
the --help output.

I suspect that the complexity of making tzselect be more verbose (to let 
users choose -t interactively?) would cost users more than it would 
benefit; after all, tzselect is already pretty complicated (which is my 
fault of course). But perhaps I'm wrong and someone could implement 
something nicely.
