To get this new example to work, this fix has to be in place in the runtime, meaning that we will need to produce 3.9.2 release for people to be able to successfully run the timezone example themselves.  We can discuss the timing of 3.9.2 creation and release relative to other things that committers and contributors are currently working on.
