查询语句1：
SELECT _WSTART, _WEND, count(*) AS total_count
FROM mp.clue
WHERE time_server >= '2024-02-28 00:00:00.000000000' AND time_server <= '2024-02-28 14:59:59.999999999'
INTERVAL(6h) FILL(NULL_F);

查询语句2：
SELECT _WSTART, _WEND, count(*) AS total_count
FROM mp.clue
WHERE time_server >= '2024-02-28 00:00:00.000000000' AND time_server <= '2024-02-28 14:59:59.999999999' AND clue_platform_id='402'
INTERVAL(6h) FILL(NULL_F);

问题：
查询语句2仅仅多了一个Where筛选条件，为什么会导致两条查询语句返回的时间不一致
