Unix time stamps, short (int) or long res, are always supposed to GMT 
based, as far as I know - I never seen anything different, except maybe 
in homebrew software. So it should be both calendar and P.I.T. And you 
wouldn't need the TZ storage if the date-number and number-> translation 
itself takes the TZ arg so that it can localize the Human String for you.
