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.
