Timezone problem with iCal export

Hi,

I’ve double-checked the ical calendar export and found an issue. It turns out that the Z suffix (for UTC) is being used in the timestamps, even though the timezone is already specified as Europe/Berlin. This causes the times to be incorrectly, leading to a time shift.

Example:

DTSTART;TZID=Europe/Berlin:20250213T120000Z
DTEND;TZID=Europe/Berlin:20250213T140000Z
DTSTAMP;TZID=Europe/Berlin:20250211T012043Z
LAST-MODIFIED;TZID=Europe/Berlin:20250211T012043Z

• The Z suffix indicates that the time is in UTC, but since the timezone is already set to Europe/Berlin, this creates a conflict.
• As a result, times will be shifted by one hour (or more, depending on daylight saving time). For example, if the calendar shows a time of 12:00 (noon) in Berlin but includes the Z suffix, it will incorrectly display as 12:00 UTC (which would be 13:00 in Berlin during standard time).
• This cause confusion and leading to incorrect scheduling or missed events.
• I’ve tried using the “Time conversion type: No timezone conversion (fixed to local time)” setting and adjusted the time difference as needed, but unfortunately, the issue persists. And I have tested all possible settings and configurations, but the problem remains the same. 🙁

Suggested fix:

• When the timezone is specified as Europe/Berlin, the timestamps (e.g., DTSTART, DTEND, DTSTAMP, LAST-MODIFIED) should not include the Z suffix.
• The Z suffix should only be used when the time is in UTC.

Example:

• DTSTART;TZID=Europe/Berlin:20250213T120000
• DTEND;TZID=Europe/Berlin:20250213T140000
• DTSTAMP;TZID=Europe/Berlin:20250211T012043
• LAST-MODIFIED;TZID=Europe/Berlin:20250211T012043

Please help. <3
