Subject [jira] [Created] (PHOENIX-6486) Phoenix uses JodaTime ISO calendar internally, which is incompatible with the JDK time representation
Date Mon, 31 May 2021 13:00:00 GMT
Istvan Toth created PHOENIX-6486:
------------------------------------

             Summary: Phoenix uses JodaTime ISO calendar internally, which is incompatible
with the JDK time representation 
                 Key: PHOENIX-6486
                 URL: https://issues.apache.org/jira/browse/PHOENIX-6486
             Project: Phoenix
          Issue Type: Bug
          Components: core
    Affects Versions: 4.16.1, 5.1.1
            Reporter: Istvan Toth


Phoenix does a lot of internal Time processing using JodaTime.
However, the default Chronology for JodaTime is ISO, 
while the default chronology used by the JDK is GregorianJulian 
https://www.joda.org/joda-time/cal_gj.html

This causes pre-cutover dates to completely handling to fail spectacularly:
