我有一些类似这样格式的数据：

(id, time, value)

给出以下模拟数据（可能有重复数据）：

("a1", "2022-06-28 00:00:00", "0.23"), // The time interval is 15 minutes, and there is only 24-hour data of the day
("a1", "2022-06-28 00:15:00", "0.89"),
...
("a1", "2022-06-28 23:59:59", "0.11"),

("b1", "2022-06-28 00:00:00", "0.23"), 
("b1", "2022-06-28 00:15:00", "0.89"),
...
("b1", "2022-06-28 23:59:59", "0.11"),

("c1", "2022-06-28 00:00:00", "0.23"), 
("c1", "2022-06-28 00:15:00", "0.89"),
...
("c1", "2022-06-28 23:59:59", "0.11"),

假设现在是2022-06-28 16:00:00，我想计算1小时、45分钟、30分钟、15分钟前和现在的数据。
输出应如下所示：

("a1", "2022-06-28 15:00:00", "1"),
("a1", "2022-06-28 15:15:00", "1"),
("a1", "2022-06-28 15:30:00", "1"),
("a1", "2022-06-28 15:45:00", "1"),
("a1", "2022-06-28 16:00:00", "1"),
("b1", "2022-06-28 15:00:00", "1"),
("b1", "2022-06-28 15:15:00", "1"),
("b1", "2022-06-28 15:30:00", "1"),
("b1", "2022-06-28 15:45:00", "1"),
("b1", "2022-06-28 16:00:00", "1"),
("c1", "2022-06-28 15:00:00", "1"),
("c1", "2022-06-28 15:15:00", "1"),
("c1", "2022-06-28 15:30:00", "1"),
("c1", "2022-06-28 15:45:00", "1"),
("c1", "2022-06-28 16:00:00", "1"),

如何编写Flink程序？最好用Java或Scala编写。如果你能给我一些代码片段，我将非常感激!
