[tz] [PATCH 4/4] yellow flags

[David Patte ₯]

For some reason I did not receive [Patch 3/4]. Was it sent out?

Also I would like, at least temporarily, to raise a yellow flag on patch 
4/4.

Numerous products allow their users to use the current tz identifiers 
and links directly and I need a short time to study the consequences of 
the change proposed for currently installed users. A case in point is 
Drupal, one of the top CMS systems in installed base (after Wordpress), 
which allows all users to select their own timezone identifier. There 
are currently about 1 million Drupal websites installed, many of which 
have hundreds or thousands of users.
