-----------------------------------------------------------
The verification is failing since the CMake version used by Travis is quite
old. I will push a version that works with older CMake versions.

> [C++] Cache timezone information in the library.
> ------------------------------------------------

> Key: ORC-218

> Project: ORC
> Issue Type: Improvement
> Reporter: Martin Grund
>
> Right now, for every lookup of a timezone, the library will go to disk and
> parse the timezone file. While the results are cached, doing these system
> calls should be avoided in environments with restricted system calls.
> I prepared a patch that will at build time load all the time zone files into
> the binary and instead of accessing disk for the TZ information will simply
> load the buffer from memory. In addition this allows the user to compile the
> library with a static timezone to be assumed for local use. This comes in
> handy to avoid yet another set of system calls to assume the local timezone.
> The feature can be controlled using the following CMake flags
> * NO_EMBEDED_TZ_DB - to turn it off, by default is on
> * STATIC_TZ=VAL - where val is a name of a timezone.
> I'll create a PR for code-review.
> Would be great if you could consider this patch.
