Summary
Most European countries moved clocks forward one hour on Sunday, marking the start of daylight saving time (DST), a practice increasingly criticized.
Originally introduced during World War I to conserve energy, DST returned during the 1970s oil crisis and now shifts Central European Time to Central European Summer Time.
Despite a 2018 EU consultation where 84% of nearly 4 million respondents supported abolishing DST, implementation stalled due to member state disagreement.
Poland, currently holding the EU presidency, plans informal consultations to revisit the issue amid broader geopolitical priorities.
China spans five geographic time zones and it does cause some pain to those living far away from Beijing. It’s not a great system.
Because Beijing should be using Chongqing time, yes, then the offset of clock noon to natural noon would be at most something like ±1.5 hours.
