BST (British Summer Time) clock change

Just a quick reminder to let all those who live in a country where BST (British Summer Time) has started. The clocks advance 1 Hour
Many thanks

After this change I feel so tired. I can’t get used to.

Who changes the clocks anymore? All of mine change automatically.
My iPhone, my computer, my car. I guess Ill have to change my microwave, but that’s about it.
