Subject [jira] [Created] (DRILL-3385) Max. fractional seconds precision less than standard (should be >= 6; is 3)
Date Fri, 26 Jun 2015 05:45:04 GMT
Daniel Barclay (Drill) created DRILL-3385:
---------------------------------------------

             Summary: Max. fractional seconds precision less than standard (should be >=
6; is 3)
                 Key: DRILL-3385
                 URL: https://issues.apache.org/jira/browse/DRILL-3385
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Daniel Barclay (Drill)


Drill's maximum fractional seconds precision is less than the minimum specified by the SQL
standard.

ISO/IEC 9075-2:2011(E) Annex B item 35 subitem p (p. 1329) says:

bq.The maximum value of <time fractional seconds precision> is implementation-defined,
but shall not be less than 6.

However, Drill's representation of DAY/HOUR/MINUTE/SECOND intervals seems to carry only integer
milliseconds (for only 3 decimal digits of fractional seconds precision).

(Time and timestamp values probably also carry only integer milliseconds.)
