> *Sequence time field steps for date start/end looks strange in spark as follows:*
> scala> sql("select explode(sequence(cast('2011-03-01' as date), cast('2011-03-02' as date), interval 1 hour))").head(3)
> res0: Array[org.apache.spark.sql.Row] = _Array([2011-03-01], [2011-03-01], [2011-03-01])_ *<- strange result.*
> scala> sql("select explode(sequence(cast('2011-03-01' as date), cast('2011-03-02' as date), interval 1 day))").head(3)
> res1: Array[org.apache.spark.sql.Row] = Array([2011-03-01], [2011-03-02])
> *While this behavior in Prosto make sense：*
> presto> select sequence(date('2011-03-01'),date('2011-03-02'),interval '1' hour);
> Query 20200624_122744_00002_pehix failed: sequence step must be a day interval if start and end values are dates
> presto> select sequence(date('2011-03-01'),date('2011-03-02'),interval '1' day);
> _col0
> [2011-03-01, 2011-03-02]
