-------------------------------------
Assignee: Riza Suminto
> Time string with signed TZH token preceded by dash cannot be cast to timestamp
> ------------------------------------------------------------------------------
>
> Key: IMPALA-9280
> URL: https://issues.apache.org/jira/browse/IMPALA-9280
> Project: IMPALA
> Issue Type: Bug
> Components: Backend
> Affects Versions: Impala 3.3.0
> Reporter: Jozsef Koza
> Assignee: Riza Suminto
> Priority: Minor
> Labels: newbie
>
> Given a time string containing a TZH token with a sign which is preceded
> immediately by a dash delimiter cannot be cast to timestamp.
> h3. To reproduce
> Execute {code:sql}
> select cast("08:00-+01" as timestamp format "HH:MI-TZH");{code} which results
> in *NULL*.
>
> ----
> It seems like the delimiter is incorrectly recognised as the sign of the
> timezone offset hour which prevents parsing the TZH value.
> Adding an additional delimiter (other than dash itself) between the dash
> separator and the sign in the time string makes cast working.
> Executing
> {code:sql}
> select cast("08:00- +01" as timestamp format "HH:MI-TZH");{code}
> results in *08:00:00*.
