Currently I have one table and one date record with a format of (2011-05-25 23:00:00.000) I would like to create a time dimension that includes Years, Quarters and Months as it will be easier for reporting on. What is the easiest way to do this ?

Create a view in SQL and base your dimension off that. You might want to write this to a table to give you some flexibility to name quarters or semesters etc

select
Year(GetDate()) As Year_Key
, Year(GetDate()) * 100 + Datepart(qq,GetDate()) As Quarter_Key
, Year(GetDate()) * 100 + Datepart(mm,GetDate()) As Month_Key
, DateName(mm,GetDate()) + ' ' + Cast(Year(GetDate()) As VarChar) As Month_Name

Here's a script to create a time dimension:

Script to Populate Date Dimension, without Using a Cursor

I wouldn't stop at the month level. I would create the dimension to the date level. You never know if the requirements for reporting change and this way you'll be ready. And it aren't that many rows.
