This might get you started (since you didn't provide table definition and sample data, I went ahead and made some myself):
with yourtable(id,dateattribute)
as (select id
,dateattribute
from (values( 1,cast('2016-12-21 13:20:45' as datetime))
,( 2,cast('2016-12-21 13:20:57' as datetime))
,( 3,cast('2016-12-21 13:21:03' as datetime))
,( 4,cast('2016-12-21 13:24:14' as datetime))
,( 5,cast('2016-12-21 13:24:27' as datetime))
,( 6,cast('2016-12-22 13:20:45' as datetime))
,( 7,cast('2016-12-22 13:20:57' as datetime))
,( 8,cast('2016-12-22 13:21:03' as datetime))
,( 9,cast('2016-12-22 13:24:14' as datetime))

) as yourtable(id,dateattribute)
)
select a.id
,a.dateattribute
,convert(varchar(10),a.dateattribute,101)

+right(convert(varchar(20),a.dateattribute,100),7)
