[GreenKeys] Military Time -vs- UTC

[WA5CAB--- via GreenKeys]

Another thing that indicates that the information on that website was 
written by an unwashed US civilian is that I never heard anyone but a US civilian 
refer to the 24-hour clock as "military time". Although other countries do 
sometimes or even mostly use the 12-hour clock, most people living in them 
know about the 24-hour clock and don't automatically call it "military time". 
The first times I ever heard the time being routinely reported on the 
24-hour system was probably on either the BBC or maybe Radio Havana.
