Wrong Result from Tiflash in processing timestamp

## Bug Report

Please answer these questions before submitting your issue. Thanks!

### 1. Minimal reproduce step (Required)

```sql
Drop table if exists t1;
CREATE TABLE t1 (
id INT PRIMARY KEY AUTO_INCREMENT,
col1 timestamp DEFAULT NULL
);

ALTER TABLE t1 SET TIFLASH REPLICA 1;
```

### 2. What did you expect to see? (Required)

I find that the returned information is inconsistent across two queries.

### 3. What did you see instead (Required)

```sql
mysql> SELECT /*+ READ_FROM_STORAGE(TIFLASH[t1])*/
-> col1,
-> ADDDATE(col1, INTERVAL 12 HOUR_MINUTE) AS modified_col1,
-> CASE
-> WHEN ADDDATE(col1, INTERVAL 12 HOUR_MINUTE) IS NULL THEN 'NULL VALUE'
-> ELSE 'VALID VALUE'
-> END AS value_status,
-> LENGTH(col1) AS col1_length,
-> CONCAT(ADDDATE(col1, INTERVAL 12 HOUR_MINUTE), ' processed') AS processed_value
-> FROM t1
-> WHERE
-> ADDDATE(col1, INTERVAL 12 HOUR_MINUTE) IS NULL
-> OR LENGTH(col1) > 5;
ERROR 1105 (HY000): other error for mpp stream: Code: 0, e.displayText() = DB::TiFlashException: date_add function does not support unit HOUR_MINUTE yet., e.what() = DB::TiFlashException,
