Tsql 汇总自定义时间设置之间的项目

我们需要按天计算小时前10分钟和小时后10分钟发生的项目数。我们有一个单独跟踪项目的表。理想情况下，我希望输出如下所示，但完全接受其他建议

Table - Attendance
Att_item    timestamp
1       2012-09-12 18:08:00
2       2012-09-01 23:26:00
3       2012-09-23 09:33:00
4       2012-09-11 09:43:00
5       2012-09-06 05:57:00
6       2012-09-17 19:26:00
7       2012-09-06 10:51:00
8       2012-09-19 09:42:00
9       2012-09-06 13:55:00
10      2012-09-05 07:26:00
11      2012-09-02 03:08:00
12      2012-09-19 12:17:00
13      2012-09-12 18:14:00
14      2012-09-12 18:14:00

Output
Date        Timeslot_5pm  Timeslot_6pm    Timeslot_7pm
9/11/2012        11           22              22

这只写了一个专栏（好吧，4，但你明白我的意思）

如果DATEPART（mi，FTSdate）>=50或DATEPART（mi，FTSdate）=50或DATEPART（mi，FTSdate）您的要求并不完全清楚，但如果您只想计算20分钟窗口中的记录数：
