+### description
+
+TIME type
+ Time type, can appear as a query result, does not support table storage
for the time being. The storage range is `[-838:59:59, 838:59:59]`.
+ Currently in Doris, the correctness of TIME as a result of calculations is
guaranteed (e.g., functions such as `timediff`), but **manual CAST generation
of the TIME type is not recommended**.
+
+### example
+
+```sql
+mysql> select cast('100:00:00' as time);
++---------------------------+
+| cast('100:00:00' as TIME) |
++---------------------------+
+| 100:00:00 |
++---------------------------+
+1 row in set (0.11 sec)
+
+mysql> select timediff('2020-01-01', '2000-01-01');
++------------------------------------------------------------------------------------+
+| timediff(cast('2020-01-01' as DATETIMEV2(0)), cast('2000-01-01' as
DATETIMEV2(0))) |
Review Comment:
我们写文档，举例子的时候，首先得先举个正常的例子啊。。。比如先timediff 两个正常的值，结果是多少；然后再举一个timediff
的范围太大是异常值的时候的结果啊
