Wrong ics for Europe/Dublin

[mikescandy]

Steps to reproduce

1. open file calendar/timezones/zones.json
2. search for europe/dublin
3. compare with europe/london

Expected behaviour

IST and BST should have the same settings for standard and daylight

Actual behaviour

IST have swapped standard with daylight
see also https://github.com/ical4j/ical4j/blob/cd29ee1884dac701eeb1680582d5718b7f0f6258/src/main/resources/zoneinfo/Europe/Dublin.ics

this also causes that events synced with davx have wrong date and time. namely, events appear in the previous day, at 10pm or 11pm based on daylight/standard time.

Calendar app

2.1.2
Nextcloud Version: (see admin page, e.g. 17.0.2)
20

I skipped a bunch of steps here as I don't think they should be relevant.

Is this still the case for you?

I compared the values, seems they're still different.
