>          Issue Type: Improvement
>          Components: Backend
>    Affects Versions: Impala 2.0

> We always use the non-codegen'd versions of from_utc_timestamp, to_utc_timestamp, and DateAddSub() because there are problems JITing these functions. It might be worth trying again at some point, e.g. if/when we switch to MCJIT.
