I discovered this little bit of useless information today.
Up until sometime in 1970, Greenwich Mean Time (GMT) was the standard term utilised for time with no time zone offset. During 1970, the International Telecommunication Union (ITU), devised the coordinated universal time (UTC) system.
The ITU wanted a single abbreviation for Coordinated Universal Time in order to reduce any confusion in multiple languages. The ITU could not come to a unanimous agreement on either the English acronym (CUT) or the French acronym (TUC), so the acronym UTC became the agreed-upon compromise.
So there we have it – useless trivia.
