current_timestamp zone invalid when use stream load way

[lukoou3]

Steps to reproduce the behavior (Required)

1. zone set

SET global time_zone = '+0:00';

SHOW VARIABLES LIKE '%time_zone%';
+------------------+---------------+
| Variable_name    | Value         |
+------------------+---------------+
| system_time_zone | Asia/Shanghai |
| time_zone        | +00:00        |
+------------------+---------------+

2. create table

create table if not exists test.test_details(
    id bigint not null,
    name string,
    str_default1 string default '',
    str_default2 string default 'a',
    int_default1 bigint default '0',
    int_default2 bigint default '1',
    datetime_default1 datetime default '1970-01-01 00:00:00',
    datetime_default2 datetime default current_timestamp
)
DUPLICATE KEY(id)
DISTRIBUTED BY HASH(id) BUCKETS 1
PROPERTIES (
    "replication_num" = "1"
);

3. insert sql way

insert into test.test_details(id, name) values
(1, 'name1'),
(2, 'name2')
;

+------+-------+--------------+--------------+--------------+--------------+---------------------+---------------------+
| id   | name  | str_default1 | str_default2 | int_default1 | int_default2 | datetime_default1   | datetime_default2   |
+------+-------+--------------+--------------+--------------+--------------+---------------------+---------------------+
|    1 | name1 |              | a            |            0 |            1 | 1970-01-01 00:00:00 | 2024-11-07 06:09:21 |
|    2 | name2 |              | a            |            0 |            1 | 1970-01-01 00:00:00 | 2024-11-07 06:09:21 |
+------+-------+--------------+--------------+--------------+--------------+---------------------+---------------------+

4. stream load way

curl  --location-trusted -u root: -T test_details.json -H "format:json" -H "columns:id,name" http://127.0.0.1:8061/api/test/test_details/_stream_load

+------+-------+--------------+--------------+--------------+--------------+---------------------+---------------------+
| id   | name  | str_default1 | str_default2 | int_default1 | int_default2 | datetime_default1   | datetime_default2   |
+------+-------+--------------+--------------+--------------+--------------+---------------------+---------------------+
|    1 | name1 |              | a            |            0 |            1 | 1970-01-01 00:00:00 | 2024-11-07 14:10:58 |
|    2 | name2 |              | a            |            0 |            1 | 1970-01-01 00:00:00 | 2024-11-07 14:10:58 |
+------+-------+--------------+--------------+--------------+--------------+---------------------+---------------------+

Expected behavior (Required)

datetime_default2 column store the current UTC time

Real behavior (Required)

datetime_default2 column store the current Asia/Shanghai time when use stream load way
