确定其他值是否在当前值的范围内

我有一张表格，内容如下

Tbl_Transactions
ID       Date        Hour        Minute       Location        CardID
1        20130101    1           1            a               123456

小时是24小时。我想要一个SQL查询，它返回在+ -5分钟时间窗口内同一位置的同一张卡上发生的任何事务。我没有GROUP BY语句或任何问题，我只是无法弄清楚5分钟时间窗口背后的逻辑。

到目前为止我所做的是创建一个MinutesSinceMidnight字段= 60 *小时+分钟以获得恒定的时间刻度。然后我创建了RoundMin = Round（MinutesSinceMidnight / 5）* 5和CeilingMin。然后，我使用两个值之一检查重复项。但是，这会产生不一致的时间范围。在任何一个刻度上，分钟= 53将与分钟= 50匹配，但是匹配分钟= 57，例如。

有人可以帮我提供所需的逻辑吗？
