Times are still not right when DST is on

    The hours are still one off when daylight save time is on.

    I am at timezone “Europe/Berlin” which means in winter times GMT+1 and in summer times GMT+2.

    Instead of doing fancy time calculations within the plug-in, you could simply treat all times as they are (local time with timezone) and add a timezone header to the ics file to specify DST

    DTSTART;TZID=Europe/Berlin:20080625T090000

    BEGIN:VCALENDAR
    …
    BEGIN:VTIMEZONE
    TZID:Europe/Berlin
    X-LIC-LOCATION:Europe/Berlin
    BEGIN:DAYLIGHT
    TZOFFSETFROM:+0100
    TZOFFSETTO:+0200
    TZNAME:CEST
    DTSTART:19700329T020000
    RRULE:FREQ=YEARLY;BYMONTH=3;BYDAY=-1SU
    END:DAYLIGHT
    BEGIN:STANDARD
    TZOFFSETFROM:+0200
    TZOFFSETTO:+0100
    TZNAME:CET
    DTSTART:19701025T030000
    RRULE:FREQ=YEARLY;BYMONTH=10;BYDAY=-1SU
    END:STANDARD
    END:VTIMEZONE
