| # tzdata packages and templates |
| |
| This directory contains the GN templates that provide data files for packages |
| and underlying programs that need to load IANA timezone data as provided by |
| the [ICU](https://home.unicode.org) library. |
| |
| ## `icu_tzdata_resource` |
| |
| NOTE: Most components should not use this rule to consume tzdata. Instead, |
| use the [tzdata directory capability][icu-data] to get the latest tzdata |
| provided by the platform. |
| |
| This rule adds the files `metaZones.res`, `timezoneTypes.res`, and |
| `zoneinfo64.res` to a package under the path |
| `/pkg/data/tzdata/icu/{data_version}/{format}/`. |
| |
| There will also be a file at `/pkg/data/tzdata/revision.txt` containing the |
| time zone database revision ID, e.g. `2019c`. |
