> 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.)
