Have got a reply back from the Tongan news site http://matangitonga.to/

They had a director that sits on the committee that decides this, but ultimately it goes the PM's office. They have said they want to write an article so that their readers know what is going on. This is a very good way of progressing this.

As soon as they know we should find out, but from the papers view point, DST was not so popular.

I will send them some info on why if they do, it is good for all to decide more than 2 weeks prior. Preferably the normal state should be a year in advance (for airlines).

Does IATA indeed have a source of authoritative information that isn't public? Or do they do what IANA does in the absence of authoritative information, i.e., guess? In other words, are we dealing simply with two different guesses that went in different directions?

That's my guess, yes.

(Couldn't resist....)

I have privately emailed a question about this to the Tonga Consulate General in San Francisco.
