[jira] [Updated] (ARROW-13168) [C++] Timezone database
configuration and access
[ https://issues.apache.org/jira/browse/ARROW-13168?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rok Mihevc updated ARROW-13168:
-------------------------------
Description:
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"
For more context see: [ARROW-12980|https://github.com/apache/arrow/pull/10457] and [PEP 615|https://www.python.org/dev/peps/pep-0615/#sources-for-time-zone-data].
