Fixed
- The read-only calendar export feed (webcal/ICS) now keeps the local start time of recurring events across daylight-saving changes. Series synced from CalDAV with a time zone are exported with that zone (
DTSTART;TZIDplus a generatedVTIMEZONE) instead of a fixed UTC time, so calendar apps subscribing to the feed no longer show them an hour off in the opposite season (#549).
