Events do not appear as "all day" events but as one hour events at midnight

[a3nm]

Hello,

Thanks a lot for developing this great application!

I’m having the following issue. I am subscribed to a calendar containing events like the following:

BEGIN:VEVENT
DTSTART;TZID=Europe/Paris:20160101
DTEND;TZID=Europe/Paris:20160101
DTSTAMP:20140414T160249Z
UID:JF60
CLASS:PUBLIC
CREATED:20140414T160249Z
DESCRIPTION:Jour férié: Jour de l'an
LAST-MODIFIED:20140414T160249Z
LOCATION:-
SEQUENCE:0
STATUS:CONFIRMED
SUMMARY:Jour férié: Jour de l'an
TRANSP:OPAQUE
END:VEVENT

These events show up in my calendar (stock Calendar application on CyanogenMod 13.0-20160918-NIGHTLY-oneplus3) as one hour events from midnight to 1 AM, not as full day events. Is this a bug? Is there any way to fix this?

Thanks a lot!

This is most likely not a bug in icsdroid, but the generated calendar data is bad.

RFC 5545, p. 54:

For cases where a “VEVENT” calendar component specifies a “DTSTART” property with a DATE value type but no “DTEND” nor “DURATION” property, the event’s duration is taken to be one day. For cases where a “VEVENT” calendar component specifies a “DTSTART” property with a DATE-TIME value type but no “DTEND” property, the event ends on the same calendar date and time of day specified by the “DTSTART” property.

See this SO post so better only use

DTSTART;VALUE=DATE:20100101
DTEND;VALUE=DATE:20100101

[rfc2822]

Thanks @kralo for checking the iCalendar. The default type of DTSTART is indeed DATE-TIME, so @a3nm if you want to specify a DATE, use VALUE=DATE. If you didn’t generate the iCalendar yourself, please contact the one who generated it (and provide this thread as reference).
