Calendars just seem to be a big bag of hurt on the Jolla.

Today I've been trialling the integrated calendar and contacts that's now in cPanel 11.50. It's based on SabreDAV. It's utterly flawless so far syncing between my Mac and our servers (I run a web hosting company so we're rolling this out to our customers).

Apple's Calendar, Contacts and Reminders apps work flawlessly.
BusyCal, BusyContacts and Fantastical work flawlessly.
My Android phone using Marten Gajda's SmoothSync apps work flawlessly.
An iPad worked flawlessly.

On the Jolla (running 1.1.6.27 - the current 'safe' release), on first sync of a brand new calendar the single event I've put in there is 1 hour out - it's getting confused by DST seemingly so an event set for 3pm ends up as 4pm.

If I edit the event on the Jolla and manually sync, it disappears from the Jolla though thankfully not from the server. The edit never reaches the server.

This is similar to what I've had on ownCloud and Apple's iCloud so it's not SabreDAV's fault. It's been like this for as long as they said they'd "implemented" CalDAV support though initially you couldn't even get the list of calendars from iCloud.

...and my Jolla goes back in the drawer because of this.

Can someone at Jolla buy Chris Adams a Mac so he can test CalDAV/CardDAV properly and if they want to test it against a cPanel server I'll happily provide one for them for free.
