Populate Time Dimension of AdventureWorksDW Sample Database and use it in your Datawarehouse/cube

In one of my current data warehouse projects I wanted to use a time dimension. The time dimension structure I wanted was very similar to the one available with AdventureWorksDW but it has the date only till year 2004.

I had written a simple SP to populate the time fields. If anyone has a similar requirement you can try it.
