----------------------------------
Summary: [C++] Timezone database configuration and access
Key: ARROW-13168
URL: https://issues.apache.org/jira/browse/ARROW-13168
Project: Apache Arrow
Issue Type: Bug
Components: C++
Reporter: Rok Mihevc
Note: currently timezone database is not available on windows so timezone aware
operations will fail.
We're using tz.h library which needs an updated timezone database to correctly
handle timezoned timestamps. See [installation
instructions|https://howardhinnant.github.io/date/tz.html#Installation].
We have the following options for getting a timezone database:
# local (non-windows) OS timezone database - no work required.
# arrow bundled folder - we could bundle the database at build time for
windows. Database would slowly go stale.
# download it from IANA Time Zone Database at runtime - tz.h gets the database
at runtime, but curl (and 7-zip on windows) are required.
# local user-provided folder - user could provide a location at buildtime.
Nice to have.
# allow runtime configuration - at runtime say: "the tzdata can be found at
this location"
