"New Time Proposed" not available on Mac OS

Hello all,

I am using Mac OS X Mail and Calendar apps and sometimes receive "New Time Proposed" emails as a response to a calendar even that I sent out. The issue is that Mail doesn't show you the details of the new time proposed (and neither is Calendar). I am wondering if anyone knows of any way to "parse" it (don't mind even running a script to find out...) so I'll finally know what time was proposed...

Thanks!!
