针对欧盟时钟调整僵局，提出设立UTC+2的统一中欧和东欧时间（CEET），通过中欧永久夏令时与芬兰-波罗的海集团永久标准时间自然趋同，消除跨境经济摩擦。
AI中文摘要：
欧盟废除每年两次时钟调整的努力已陷入停滞。我们认为，这一僵局为大陆统一提供了一个历史性机遇。天文学分析表明，时钟与太阳时严格对齐并无必要；在高纬度地区，极端的季节性变化使得早晨与傍晚日光的争论在物理上无关紧要。现实世界的例子表明，社会能无缝适应永久的太阳时偏移。我们提议设立统一的“中欧和东欧时间”（CEET），即UTC+2。若中欧采用永久夏令时，而芬兰-波罗的海集团保留永久标准时间，这一方案将自然趋同，使绝大多数成员国在单一时钟下同步，并消除跨境经济摩擦。
英文摘要：
The EU's effort to abolish biannual clock changes has stalled. We argue this deadlock presents a historic opportunity for continental unification. Astronomical analysis demonstrates that strict alignment between clock and solar time is unnecessary; at high latitudes, extreme seasonal variations render the morning-versus-evening daylight debate physically irrelevant. Real-world examples demonstrate that societies adapt seamlessly to permanent solar offsets. We propose establishing a unified Central and Eastern European Time (CEET) at UTC+2. This converges naturally if Central Europe adopts permanent summer time while the Finnish-Baltic bloc retains permanent standard time, synchronizing the vast majority of member states under a single clock and eliminating cross-border economic friction.
