Does SQL Server 2008 store the creation date of execution plans?

Question

We recently upgraded an application we use, which involved modifying the schema for the database. These changes could have forced cached execution plans to be discarded. If SQL Server was forced to create a bunch of new plans, this could have slowed down the user experience. I'd like to find out if this was the case.

So, my question is, does SQL Server 2008 store the creation date of cached execution plans? The management view sys.dm_exec_cached_plans doesn't have any date fields, so I suspect not.
