Thanks for the heads-up; this will cause the tz database to go wrong
in Cuba this weekend. I found a Cuban news source for the story too.
Here's a proposed patch to the tz database to handle this issue, along
with a couple of other minor pending issues that do not affect any
time stamps:
* Add a cross reference comment from Europe to Asia for Georgia.
* The legal date of the change in Mato Grosso this year was Oct 1, not Oct 4.
