| # Time Zone Version Parrot |
| |
| The TZ Version Parrot simply announces the release version (e.g. `2015d`, |
| `2019a`) of the ICU time zone data that it loaded. |
| |
| ## Instructions |
| |
| * Display the version of time zone from the `icudtl.dat` monolithic file: |
| ```shell |
| fx shell "run fuchsia-pkg://fuchsia.com/tz_version_parrot#meta/tz_version_parrot.cmx" |
| ``` |
| |
| Sample output: |
| ```text |
| Squawk! TZ version (from icudtl.dat) is: |
| 2019a |
| ``` |
| |
| * Display the version of time zone from time zone `.res` files, if available: |
| ```shell |
| fx shell "run fuchsia-pkg://fuchsia.com/tz_version_parrot#meta/tz_version_parrot_with_tzdata.cmx" |
| ``` |
| |
| ## Config data |
| |
| In order for `tz_version_parrot_with_tzdata.cmx`, which attempts to load `.res` |
| files, to work, the product being built must include those resource files using |
| a `icu_tzdata_config_data` GN rule that places them in the expected location |
| (see `kTzdataDir` in [`main.cc`](main.cc)). |
| |
| The actual `.res` files live in |
| [`//third_party/icu/tzres`](../../../third_party/icu/tzres). |
| |
| ## Testing |
| |
| Run |
| ```shell |
| fx run-test tz_version_parrot_test |
| ``` |
