WordPress and the wintertime trap for scheduled posts

[German]In the night of October 31, 2021, clocks in Europe will be changed back to winter time (standard time). Currently WordPress is still running on daylight saving time. I have now noticed a small problem when scheduling publications. I wanted to schedule a post for 11/1/2021 at 0:10am and uploaded it to the blog using an external tool. In the dashboard, the post appeared to publish on 10/31/2021 at 11:10pm. Thought at first that I had set the wrong date, until it occurred to me that the winter time changeover by WordPress is still unaccounted for. I then scheduled the post for 11/1/2021 at 1:10am, so the dashboard then shows the publish date as 11/1/2021 at 0:10am. On 10/31/2021, the publish time will probably change to 1:10am.
