> For humans, not so much. It works fine for pilots and many other industries populated by human beings. Why exactly doesn't it work for humans again? Can you

  I would ask how many times you've been sound asleep at 2AM, your local time, and woken up by a phone call from someone in the middle of their day. I used to have a phone with a Seattle area code in the GMT+5 time zone, and the only practical solution was to turn the ringer volume off at night. The military and aviation are special cases because they're specifically trained to use zulu time for professional purposes in a certain set of circumstances and situations. I'm fairly sure you won't find airline pilots scheduling their family Thanksgiving dinner in zulu time. The specific circumstances where it does work for humans is where it's known that UTC is the standard for some set of equipment, such as a person looking at a traffic chart for an incoming DDoS and going "yup, looks like that began at about 0300 UTC on Feb 2nd, so it started affecting the customer at 10PM Eastern on Feb 1st"
