Subject [jira] [Commented] (HIVE-4525) Support timestamps earlier than 1970 and later than 2038
Date Mon, 13 May 2013 19:29:16 GMT

    [ https://issues.apache.org/jira/browse/HIVE-4525?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13656271#comment-13656271

Mikhail Bautin commented on HIVE-4525:
--------------------------------------

[~ehans]: switching to long nanosecond timestamps would definitely be a much nicer solution,
but don't you think it would break backward-compatibility for timestamps serialized using
the old format?

> TimestampWritable currently serializes timestamps using the lower 31 bits of an int.
This does not allow to store timestamps earlier than 1970 or later than a certain point in
2038.
