Time Zone Version Parrot

The TZ Version Parrot showcases loading ICU time zone data (TZData) from various sources, then simply announces the release version (e.g. 2015d, 2019a) of the current TZData.

Building

If these components are not present in your build, they can be added by appending --with //examples to your fx set command. For example:

$ fx set core.x64 --with //examples --with //examples:tests
$ fx build

If you do not already have one running, start a package server so the example components can be resolved from your device:

$ fx serve

Running

The time zone data loading examples are implemented as test cases. To run one of the test components defined here, provide the package name to fx test:

• C++

  $ fx test tz-version-parrot-cpp
  

• Rust

  $ fx test tz-version-parrot-rust
  

Use cases

This example showcases the following cases:

• Initializing ICU with the system default TZData
• Initializing ICU with TZData from the build configuration (icu_tzdata_config_data)
• Initializing ICU with TZData from the local package (resource)

You can find the platform's TZDara .res files in //third_party/icu/tzres.
