Order Time SQL Server

Let’s say you want to order these times below. of course  a simple “order by” will not do it,  what you need is the query  given below

1:00 PM,  1:30 PM,  10:00 AM, 10:30 AM, 11:00 AM,

11:30 AM, 12:00 PM, 12:30 PM, 2:00 PM, 2:30 PM,

3:00 PM, 3:30 PM, 4:00 PM, 4:30 PM, 5:00 PM,

5:30 PM, 6:00 PM, 6:30 PM, 7:00 PM, 9:00 AM, 9:30 AM

SELECT Time FROM tablename
ORDER BY CONVERT(SMALLDATETIME, '19990102 ' + Time )

Technically what you are doing is appending the time to a fixed date and let SQL handle the sorting.
