Subject [jira] [Commented] (TAJO-448) Timestamp should be based on unixtime
Date Mon, 23 Dec 2013 08:23:50 GMT

    [ https://issues.apache.org/jira/browse/TAJO-448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13855491#comment-13855491

Hyunsik Choi commented on TAJO-448:

Even though It is based on unix time, it can optionally has milliseconds ranging from 0 to
999999999. 32 bits and 64bits all are not enough to represent Timestamp's full representation.
64bit log may be a temporal solution. It may be OK because currently we can only use timestamp
values during query processing, and we cannot store a data including timestamp type to any
