Jesus Camacho Rodriguez created ORC-340:
-------------------------------------------
Summary: ConvertTreeReaderFactory does not take into account
timezone information
Key: ORC-340
URL: https://issues.apache.org/jira/browse/ORC-340
Project: ORC
Issue Type: Bug
Components: evolution
Reporter: Jesus Camacho Rodriguez
When converting timestamp/date to string group, {{toString}} is called on
{{java.sql.Date}} and {{java.sql.Timestamp}}, which pick up the default time
zone to represent the date/time as a String. This can lead to the wrong String
representation. See
{{ConvertTreeReaderFactory.StringGroupFromTimestampTreeReader}} or
{{ConvertTreeReaderFactory.StringGroupFromDateTreeReader}}.
{{StringGroupFromTimestampTreeReader}} should apply shifting, similar to
{{TreeReaderFactory.TimestampTreeReader}}.
{{StringGroupFromDateTreeReader}} should use a date formatter in UTC.
