Subject [jira] [Commented] (AVRO-739) Add Date/Time data types
Date Tue, 10 Sep 2013 16:40:54 GMT

    [ https://issues.apache.org/jira/browse/AVRO-739?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13763187#comment-13763187

Doug Cutting commented on AVRO-739:

> One could log another field with the timezone identifier for these.

>From my understanding of SQL, for TIMETZ and TIMESTAMPTZ columns, a separate timezone
is not stored per row.  Rather, the TZ in the schema only affects how dates are parsed and
displayed.  Am I wrong?  If I am correct, then the timezone should not be a field but a schema
attribute that's used by implementations when parsing and displaying values.  In all cases
I believe we should only store a single UTC timestamp per value.  Adding a distinct primitive
type for each parsing/display variant seems like a poor design choice.

> A long in binary form makes sense, but in JSON, an ISO8601 string might be more useful.

Special-casing this would rule out back-compatibility, no?
