Displaying last cube processed time in SSAS

Recently, while browsing a cube excel, an end-user asked me when was it last processed? I had no quick answer and so had to connect to the SSAS server in management studio and check the properties of the cube. This got me thinking on how to expose the cube's last processed date and time to end users through Excel or similar client tools. This is very helpful to them in that they can quickly check when was the data last added. Think about it like this. A user builds a pivot table report in Excel with a filter at top which shows when was the cube processed.
