13 ottobre 1884: sincronizzati gli orologi del mondo #accaddeoggi

Greenwich e il sistema GMT

Il 13 ottobre 1884 i rappresentanti di venticinque Stati si riunirono a Washington alla Conferenza internazionale dei meridiani per definire il calcolo del tempo intorno al globo.

Dopo un duro scontro dettato da interessi prettamente nazionalistici, i delegati giunsero alla decisione di istituire 24 fusi orari a partire dal meridiano “zero” di Greenwich, un sobborgo ad ovest di Londra celebre per il suo Osservatorio astronomico.

Nonostante alcuni adeguamenti nel corso degli anni, il sistema GMT è tuttora in vigore.
