>>> [!note] Migrated issue <!-- Drupal.org comment --> <!-- Migrated from issue #3007380. --> Reported by: [tasc](https://www.drupal.org/user/296191) Related to !11 >>> <p>Saving a node with a date-repeat ending on a certain date works like expected.<br> In Safari [11.1.2 (13605.3.8)] however, editing the same node throws an error:<br> <strong>InvalidStateError: The object is in an invalid state.</strong><br> Same issue also on 8.1.</p> <p>Furthermore the RRule wrongly stores the UNTIL-Value with a timezone-offset, which might lead to an event ending to early and confuses users by inconsistent values.</p>
