iCal returning invalid completed Tasks

[bmaehr]

Hello,

I tried to sync my tasks from Kopano with ical4j, but unfortunatly it fails with an exception. The reason is the Compled field:

COMPLETED;TZID=Europe/Amsterdam:20001008T000000

According to the specs http://ical4j.github.io/docs/ical4j/api/3.0.4/net/fortuna/ical4j/model/property/Completed.html the COMPLETED fieled has to be in UTC and the implementation fails when providing a TimeZone.

Indeed, the RFC also states that it should be printed as an utc value. https://tools.ietf.org/html/rfc5545#section-3.8.2.1

Will create a ticket for it tomorrow. If you want to provide a pr for this this would be welcome.

Meanwhile you could also have a look at https://forum.kopano.io/topic/1341/request-for-feedback-new-caldav-and-carddav-implementation-for-kopano which will eventually replace the current implementation.
