Then the UK’s equally dumb: it was 10:04 pm BST (GMT+1) cos daylight savings is a thing in most of Europe too. At least it’s synchronised across Europe[1] so you just need to remember that most[2] of North America changes a few weeks earlier.
Also, the UK says GMT/BST which is nice and clear - calling both EST and EDT “Eastern Time” makes even more of a mess!
