-------------------------------------
Summary: [DOC] Extend FROM_UNIXTIME() doc with Timezone offset
behaviour.
Key: IMPALA-10306
URL: https://issues.apache.org/jira/browse/IMPALA-10306
Project: IMPALA
Issue Type: Bug
Components: Docs
Reporter: Gabor Kaszab
FROM_UNIXTIME() accepts a format parameter that is a string that represents how
this function should format its output timestamp. This format parameter can
contain a timezone offset, however even if we provide a TZ offset in the format
parameter it won't be included in the result.
The reason is that Impala stores Timestamp without timezone in UTC and has no
information of the timezone offset.
I think it would be nice to clarify this in the docs so that the users won't
expect to get specific timezone offsets from this function as a result.
