For the very first time I tried to publish a post by setting the time I wanted it to publish via the dashboard.
I first checked my settings to make sure I was still in the right time zone (UTC + 2 for Central European Summer Time) and then set it to publish at 15.50, or about 7 hours later.
The time came and went and it didn't publish, though I did notice via manage drafts that it showed I'd edited the post around the time I wanted to publish.
Weird. Does this often happen? Did I utter the wrong incantation?
