[tz] Missing entry for Heard Island and MacDonald Islands

## What level of discussion is this?

Actually, a funny and intelligent answer from Paul.  True vacuum has no
atoms. As temperature is understood to be the measure of how much atoms
move relative to each other (or similar), it makes little sense to talk
about temperature where there are no atoms. Similarly, a long discussion
about a time zone for a place where there is nobody to look at a clock
seems futile. Small groups of temporary visitors do not count, because they
will observe whatever time they want to.  They may, for example, decide to
leave clocks at their home time zone, or set them as dictated by
geographical time or whatever.

On the other hand, if a governmental organization defines a time zone for
an area, like for HM or Siberia, then it makes sense to consider this time
zone as applying to the area.  The real question to answer is, if we want
the tz database to have a time zone for each ISO territory code or not. If
not, then UTC+5 is good enough. It is really waste of time to try to define
history of observed time for a generally inhabited island.  If yes, let's
add a time zone and define it as UTC+5 with no history.
