Tim Armstrong updated IMPALA-5279:
----------------------------------
Component/s: Backend
> More Complete ISO 8601 Date Support
> -----------------------------------
>
> Key: IMPALA-5279
> URL: https://issues.apache.org/jira/browse/IMPALA-5279
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend
> Reporter: Alan Jackoway
> Priority: Major
>
> I am trying to handle dates that came in as ISO 8601 format including a time
> zone offset and having a lot of trouble. Here are two things I expected to
> work, but did not:
> {code:sql}
> -- Casting to dates with time zone offsets. These results should be different
> select cast("2014-09-24T12:29:19 -07:00" as timestamp), cast("2014-09-24
> 12:29:19 -08:00" as timestamp);
> -- Format string for time zone offset
> select unix_timestamp("2014-09-24 12:29:19 -07:00", "yyyy-MM-dd HH:mm:ss Z")
> {code}
> There may be other gotchas around ISO-8601 handling, but those are the two I
> ran into today.
> I also couldn't find documentation on the format string for unix_timestamp,
> though it seemed to work the way
> https://docs.oracle.com/javase/6/docs/api/java/text/SimpleDateFormat.html
> does other than perhaps time zone and things I've never attempted like era.
