They might have few computers, but report claims there are millions of smartphone in the country, although they're connected to an intranet instead of internet. Not sure how those phones are going to receive updates.

And as the changes is clearly a political one, we should probably be grateful that they aren't going to implement the change immediately nor on the next day after the announcement

Thanks. In the absence of further info, let's assume the transition will be at
00:00 local time on May 5, and that the clocks will jump from 00:00 to 00:30.
Proposed patch attached. If we find out later that this assumption is wrong,
we'll need to update tzdb accordingly.

We'll need a new tzdb release shortly, of course.
