The alt-text for the XKCD comic published on 2017-08-30 notes:
Someday, some big historical event will happen during the DST changeover, and all the tick-tock articles chronicling how it unfolded will have to include a really annoying explanation next to their timelines.
here, Randall Munroe refers to minute-by-minute — or even second-by-second — timelines / reconstructions that one can find in newspapers or on websites, such as Wikipedia.
Have there been any big events that happened during DST changeover? By big event, I mean any event big enough such that it was covered with a detailed timeline (at least down to the minute) in major news media.
