Your English was good :-)

As far as we are aware, 19:30 CET is the time. If this changes, we will endeavour to update the post.

We understand that the short notice can be unhelpful, and we do already try to give as much advance notice as we can. Despite the short notice, we are receiving a lot of excellent data and feedback from these encounters and we do greatly appreciate the interest people have in helping to make certain that the PTR testing is valuable for ensuring the quality of the end result. Thanks to everyone who, despite short notice, perseveres and helps to test our upcoming content.
