Format a column containing time stamp entries to yyyy/mm/dd

SELECT s.FirstName + ' ' + s.LastName as [Student Name], g.Grade, p.Programs, g.InsertTime 
	FROM Student s
INNER JOIN dbo.SRSubmitGrades g
	on s.StudentUID = g.StudentUID
Inner JOIN Programs p
	on s.ProgramsID = p.ProgramsID
		WHERE s.ProgramsID IN ('239', '215', '243', '216', '240')
AND GRADE not in ('A', 'A-', 'B+', 'B', ' ', 'P')
	ORDER BY InsertTime;

This returns a table that for the most part is perfect however, The InsertTime Column pulls a timestamp 

e.g. 

2007-12-20 10:44:17.000

2007-12-20 14:23:12.000

2007-12-21 10:35:00.000

I have tried unsuccessfully using cast and Convert, i believe it is because it is unusable. All i really need to do is remove the Underlined: What i want it to look like is 2007/12/21

2007-12-21 10:35:00.000

Thank you for any help.

Sometimes the answer is so blindingly obvious i fail to see it. Sdog
