Cal - now with 100% more Evolution support

I mentioned in a previous post that I am working on a CalDav server (creative as always I named it LazerBunny cal), to take control of my appointments and calendaring needs. The first iteration was working decently well with Apple Calendar. During this week I fixed a few issues making it also work nicely with any calendar app that uses Evolution as its backend. There were actually not many changes needed to make this work. Authentication, hitting the endpoints, all of this worked well. But there was an issue with date filters Evolution expected to work while Apple Calendar does not really care about them. So a few hours of work and I could see all my appointments, I could add new ones that showed up on my phone and things mostly worked. Except that the Alpine base image did not have tzdata installed, so it only worked “on my machine” but not deployed to the server. apk add tzinfo did the trick and now my actual calendar I am using daily for the last week does not throw unknown time…
