> `CAST(n,TIMESTAMPTYPE)` If n is Byte/Short/Int/Long data type, Hive treat n
> as milliseconds unit , while Spark SQL as seconds unit. so the cast result is
> different,please be care when you use it.
> For example:
> {code:java}
> In spark
> spark-sql> select cast(1586318188000 as timestamp);
> 52238-06-04 13:06:400.0
> spark-sql> select cast(1586318188 as timestamp);
> 2020-04-08 11:56:28
> In Hive
> hive> select cast(1586318188000 as timestamp);
> 2020-04-08 11:56:28
> hive> select cast(1586318188 as timestamp);
