Why European clocks lagged behind while British timepieces remained perfectly synchronized

European clocks ran slow for a bit. British clocks didn't. · 4:12 · Video: Tom Scott · Watch at the source

In short: A recent power grid anomaly caused clocks across Europe to lose time. This video explores the technical reasons behind the drift and why British clocks were unaffected, all while indulging in a bit of lighthearted national pride.

The incident highlights the fragility of power grids, which rely on precise frequency regulation to keep electric clocks synchronized. When the grid frequency fluctuates, these devices—which count cycles to track time—begin to drift.

While the European power grid experienced a significant temporal anomaly, the British system remained stable. The video uses this event to examine the intersection of infrastructure reliability and the quirks of grid management, framed through a distinctly British perspective.
