It does look odd that there should be such a little island of GMT+6 in the
sea of GMT+7, but if the decision about this was restricted to Guandong,
then splitting this province in 3 parts the manner it is suggested by makes more sense. I don't know if there is any way to check if is right about this claim.

The little map I sent anyone can put in your own web page(s) as you want,
there is no copyright :-)

If you rather want to point to it, like or something like that, I
could put it up, but I haven't decided to put it up on a full web page with
reference information etc. so I think a direct inclusion in your page(s)
would be fine. Am I missing something?

I wouldn't mind creating maps of other Olson db timezones if anyone is
interested, as long as this is not too time-consuming.

That is a surprise, and looking at your map it kind of sticks out like a
sore thumb.  Why would there have been a little island of GMT+6 in the sea
of GMT+7, almost next to the GMT+8 region?

Anyway, thanks very much for the info; I'll include it in the next proposed
tz patch.  Will you have a permanent URL for that map?  If so, I'd like to
include a URL as well.
