> Project: Apache Arrow
> Issue Type: Bug
> Components: C++
> Reporter: Wes McKinney
> Assignee: Fernando Rodriguez
> Priority: Major
> Labels: beginner, pull-request-available
> Fix For: 6.0.0

> The absence of default values for {{days}} and {{milliseconds}} triggers a
> compiler warning in some compilers. This could be resolved by setting the
> struct member default values to 0
