[jira] [Created] (TAJO-1234) Rearrange timezone in date/time types

Hyunsik Choi created TAJO-1234:
----------------------------------

             Summary: Rearrange timezone in date/time types
                 Key: TAJO-1234
                 URL: https://issues.apache.org/jira/browse/TAJO-1234
             Project: Tajo
          Issue Type: Bug
          Components: data type, planner/optimizer
            Reporter: Hyunsik Choi
            Assignee: Hyunsik Choi
            Priority: Blocker
             Fix For: 0.9.1


Currently, the master branch causes unit test failures. It's because that some inconsistent timezone usages. The main purpose of this issue is to cleanup and rearrange timezone usages.

I discussed this issue with [~jungjw] at 
 * http://markmail.org/thread/qhsizgp2pnd6swjq
 * http://markmail.org/message/3nqecl34l2ayxg2x

I'll fix some parts as I mentioned in above mailing list threads.

In sum, 
 * Tajo will have only four points which consider timezone
   * query statement 
   * Input table
   * text printout in TajoCli
   * Casting from text to either time or timestamp
  * All other parts have to deal with TIME and TIMESTAMP values as UTC value
