Check New Management Pack using Powershell

Management Packs got deployed I checked the Operations Manager Eventlog for eventid 1201.
And because I do this every time when I deploy new Management Packs I created a PowerShell script to check for these events. This is why we invented PowerShell.

I wanted to know which Management Packs where deployed since the last 2 hour. No need to retrieve all deployed Management Packs.
