Reporting VM objects created during a predefined time period from VI Events object

An important auditing tool in your environment can be a report of when virtual machines were created, cloned, or deleted. Unlike snapshots, that store a created date on the snapshot, virtual machines don't have this property associated with them. Instead, you have to rely on the events log in vSphere to let you know when virtual machines were created.
