Don't agree. You'd lose any idea of what a certain time of day actually means to others. It's 2 am where you are? Why are you still up? Aren't you tired? No, now I need to know where you live and figure out what time of day... oops, can't do that anymore... figure out where the sun is positioned in your part of the world. Wtf? Wasn't that what sundials and later clocks were for in the first place? Like you say, animals live by the sun, and so do we. I don't care what the *actual* time is where you live, I only care about what part of the day it is so I can adjust my communication with you accordingly.
The only thing I want is that when people *publish* times, like for international events, they (also) use UTC. It just happens too often that people will say : the live stream will start at 7PM PST and then I have to go look up what the heck that is in my local time zone. With UTC that would be solved, you'd only need to remember your offset to UTC and that's it. (Btw, they could even just mention *their* offset to UTC, eg: 7PM PST (UTC-8), because really Americans' we here in Europe have no idea what all those abbreviations mean
