LAST-MODIFIED is not getting updated after edit an event.

It works nice on OwnDrive 8.2.2 (stable). Looks like it was a regression on vr 9.0

Okay, this issue should be splitted into two issues. The first is the wrong format, which looks a lot like an upstream issue The second is the missing update of the Last modified property

[georgehrke]

also applies to CREATED and DTSTAMP

[georgehrke]

In my opinion ical.js should take care of storing them as UTC
