Saying you were walking down the street at 2am or 3am is immediately distinct from saying you were walking down the street at 10pm or 11pm in ways many people understand. Having to qualify it with the date and geographic location and/or sunrise or sunset patterns would be a much bigger PITA than your average person will ever experience because of time zone inconsistencies. It's just not that important for most people to be able to pinpoint a timestamp to one exact time throughout the world. We've got GMT. Nothing is stopping anybody from using that to schedule their lives. There's a reason people don't.
