Description

Recently I've heard from a few users that they're getting this error:

Fatal error: Uncaught Exception: Invalid iCal date format.

I've traced it back to one particular calendar vendor whose output includes the line DTEND:None when events do not have an end date/time set.

It's my understanding/assumption that this is not a valid DTEND value. But, nevertheless, it's showing up in feeds.

Steps to Reproduce
