 Replying to [comment:16 Otto42]:
 > I wouldn't go that far. We can do it eventually, but it has to be in
 stages, across a few releases. Unit tests likely come first. Then we have
 a basic test suite to ensure nothing horrible happens by mistake.

 If extension code relies (knowingly or unknowingly) on UTC time zone being
 set it will fail if core stops doing that.

 As above we can, should, and will make ''core'' operate independently of
 this assumption. But even after that we can't stop setting UTC without
 breaking code out there.

 WordPress should never have done this in first place, but since it did it
 is stuck with it forever now.
