------------------------------------------
Assignee: (was: Daniel Barclay (Drill))
> 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
> Components: Execution - Data Types
> Reporter: Daniel Barclay (Drill)
> Fix For: Future
>
>
> 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.)
