关于时间段提取数据的有关问题

关于时间段提取数据的问题?
我的表:

id time
1 12:32:33
2 13:42:11
3 15:02:12

现在系统某个表记录着每天每隔半个小时的打卡记录,例如 13:30 ,14:00,14:30,我要提取出所有每半个小时产生的打卡记录,之间我允许有正负五分钟的误差,例如

select * from table where time>='13:25:00' and time<='13:35:00'

但是一天有24小时这么多,那是不是我就一定要这么写,有没有简单点的写法?

select * from table where time>='13:25:00' and time<='13:35:00'
union
select * from table where time>='13:55:00' and time<='14:05:00'

SQL code


select convert(datetime,convert(varchar(11),getdate(),120)) date,
    dateadd(mi,-5,convert(datetime,convert(varchar(11),getdate(),120)
        +right(100+number/2,2)+':'+right(100+number%2*30,2))) as st,
    dateadd(mi,5,convert(datetime,convert(varchar(11),getdate(),120)
        +right(100+number/2,2)+':'+right(100+number%2*30,2))) as et
from master..spt_values
where [type] = 'p' and number between 0 and 47
