Reccurent event always starts today #6425

Closed sanpii closed 1 week ago

sanpii commented 1 week ago

Steps to reproduce

  1. Create a recurrent event (with thunderbird in my case);
  2. Get the ics ressource with a recurrent event planned for tomorrow.

Expected behavior

The DTSTART attribute should be the date of the recurring instance.

Actual behaviour

The DTSTART attribute is always the creation date.

After investigation, it's not a bug.

rfc5545:

The "DTSTART" property for a "VEVENT" specifies the inclusive start of the event. For recurring events, it also specifies the very first instance in the recurrence set.
