Answer 1

您可以使用 DATE_ADD_STR(expression, n, part) 日期函数。您的查询类似于以下内容：

SELECT 
    DATE_ADD_STR(DATE_ADD_STR(old_time, 5, "hour"), 30, "minute") AS new_time, ...
FROM some_bucket

文档：

Performs date arithmetic. n and part are used to define an interval or duration, which is then added (or subtracted) to the date string in a supported format, returning the result. Parts:

• "millennium"
• "century"
• "decade"
• "year"
• "quarter"
• "month"
• "week"
• "day"
• "hour"
• "minute"
• "second"
• "millisecond"
