With universal time, the answer is meaningless without also knowing where they live. If you have a friend who is traveling and says “Oh man, I stayed up until 3AM last night.” Did they go to bed early or late? Not only do you have to clarify their normal sleep schedule, you also have to figure out where they currently are before “3AM” has any relevant meaning.
It’s objectively worse for communication. As I’ve mentioned to other posters, we already have GMT if you want to use that. Let me know how well people understand you when using only GMT for scheduling.
I’m glad GMT exists as the middle point for us to use personalized time zones, but don’t want to lose that “midday” is when the sun is high in the sky and “midnight” is partway through the dark time.
“Did they go to bed early or late?” … they went to bed x hours ago. If anything, the math is easier when your 3am is also their 3am(although am/pm would also have to go out the window). Time-zones or no doesn’t tell you when they got up or started working without you asking either.
I used to work both.
