The RDATE entries are shown at the UTC time and not shifted to the local timezone.

RDATE:20240313T081500Z -> Is shown at 8:15 (which ist UTC) and not 9:15 in Europe/Berlin timezone
RDATE:20240313T081500Z -> is shown at 7:15 (UTC) and not 9:15 in Europe/Berlin timezone

Thunderbird shows the RDATE events correctly.

The days are:
2024-01-17 shown at 9:15 -> correct
2024-03-13 shown at 8:15 -> UTC (winter time in Berlin, UTC+1h)
2024-07-03 shown at 7:15 -> UTC (summer time in Berlin, UTC+2h)
