I didn't know the politics of UTC. But makes sense, sometimes a good compromise is sometimes one that makes everybody a little bit unhappy!

On other abbreviations, folks may come across "Z", acronym "Zulu". 13:15 Z would be "thirteen fifteen Zulu". Zulu is an abbreviation of an abbreviation! When handwritten, often a "-" is drawn through the Z to make it less confusable with the number "2". Z, GMT, UTC basically all mean the same thing.
