creating all day event VALUE=DATE issue

[gstlouisgit]

I am trying to create an all day event. An example here https://datatracker.ietf.org/doc/html/rfc4791#section-7.8

I should be using this string for dtstart and dtend property VALUE=DATE:

When I try this with values below I get server error Sabre\DAV\Exception\UnsupportedMediaType: Validation error in iCalendar: The supplied value (VALUE=DATE:20240827) is not a correct DATE-TIME

Am I doing this wrong? Can you create all day events with vobject?

This systems runs Baïkal 0.9.5

        /*  BAIKAL VOBJECT   */
        $vcalendar = new VObject\Component\VCalendar([
            'VEVENT' => [
                'SUMMARY' => $model['put']['summary'],  
                'PRODID' => OWNER,
                'DTSTART' => 'VALUE=DATE:20240827',
                'DTEND' => 'VALUE=DATE:20240828',
                'DESCRIPTION' => ( isset( $model['put']['description'] ) ? $model['put']['description'] : '' ),
                'RRULE' => ( isset( $model['put']['rrule'] ) ? $model['put']['rrule'] : '' ),
                'VALARM' => [
                    'ACTION' => 'DISPLAY',
                    'TRIGGER' => '-PT' . $model['put']['alarm'] . 'M',
                ]
            ]
        ]);

var_dump($vcalendar->serialize());exit;

I finally found the flag you can use for creating the event as an all day event instead of date-time. There is no documentation for this in bikal, however the baikal examples that come with the lib package does show how to do this with anniversary vevents.

events by default are VALUE=DATE-TIME in ex. DTSTART;VALUE=DATE-TIME:19970901T130000Z In order to flag an all day it needs DTSTART;VALUE=DATE:20240830

Once vobject, baikal needs $vcalendar->VEVENT->DTSTART['VALUE'] = 'DATE'; which switches it over to DTSTART;VALUE=DATE

IF not you will see an error in the logs about date-time

Here is my example that also show if you put emtpy string in rrule it just get ignored once serialized. Hope it helps someone

        $vcalendar = new VObject\Component\VCalendar([
            'VEVENT' => [
                'SUMMARY' => $model['put']['summary'],  
                'PRODID' => OWNER,
                //'DTSTART' => new \DateTime( $model['put']['start'] ), 
                //'DTEND' => new \DateTime( $model['put']['end'] ),
                'DTSTART' => $model['put']['start'],
                'DTEND' => $model['put']['end'],
                'DESCRIPTION' => ( isset( $model['put']['description'] ) ? $model['put']['description'] : '' ),
                'RRULE' => ( isset( $model['put']['rrule'] ) ? $model['put']['rrule'] : '' ),
                'VALARM' => [
                    'ACTION' => 'DISPLAY',
                    //'DESCRIPTION' => 'alert for event "with nested alarm"',
                    'TRIGGER' => '-PT' . $model['put']['alarm'] . 'M',
                    //  ex. TRIGGER;VALUE=DURATION:-PT2H 2 hours
                    //  ex. TRIGGER;VALUE=DURATION:-P2D 2 days
                    //TRIGGER;VALUE=DATE-TIME:19970317T133000Z, /* to set a precise time */
                ]
            ]
        ]);
