[jira] [Created] (ARROW-9955) [Rust][DataFusion] Benchmark and potentially optimize the to_timestamp function

Andrew Lamb created ARROW-9955:
----------------------------------

             Summary: [Rust][DataFusion] Benchmark and potentially optimize the to_timestamp function
                 Key: ARROW-9955
                 URL: https://issues.apache.org/jira/browse/ARROW-9955
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: Andrew Lamb


As suggested by [~jhorstmann] on https://github.com/apache/arrow/pull/8142#discussion_r485468664

> I'd be interested in a benchmark of the to_string function or the kernel, maybe one for the happy case with `T` and `Z` and one for the last fallback. From my experience with Java, [parsing timestamps can be rather slow|https://github.com/jhorstmann/packedtime#benchmarks] and it might be worth writing a specialized implementation.
