Will Jones commented on ARROW-13168:
------------------------------------
I started to look at this then got busy with something else. My thought was we
might be able to achieve setting this at runtime using {{set_install}} and
{{reload_tzdb()}} ([See these
lines|https://github.com/apache/arrow/blob/dea502da05363666464e5d441cc7b5428fd964c8/cpp/src/arrow/vendored/datetime/tz.h#L1307-L1308]).
Not 100% sure this will work; there seems to be [some issue that this supports
the text format and not some binary
format|https://github.com/HowardHinnant/date/issues/626] (I have some more
investigating to do).
> [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
> Assignee: Will Jones
> Priority: Major
> Labels: timestamp
>
> 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].
