I agree, besides with most of the tech we use people can set their notifications to not get disturbed while they are sleeping. I don't really care if my lunch is at 20:00 or 12:00, but when I work across time zones and there is a mismatch because of seasonal time change it can get really infuriating. Pilots adopted UTC for similar reasons a long time ago, except in their case the potential mixups had a high risk of fatality rather than annoyance and inconvenience.
