| Except if we did abolish time zones rather than asking Google "what time is it in Melbourne" you ask it "is it the waking hours in Melbourne". In either case you don't know what time to call Melbourne. You either need to know a complicated and inconsistent system of time zones, or you just ask the same question in terms of when the sun rises and sets. You don't get out of asking a question, you don't lose any information (there is a 1 to 1 equivalence between what time it is somewhere and when its noon there, you could ask either question and have the exact same thought process comparing a time to "safe" hours to call someone). That article argues that the current system is some miraculous saver of sanity by solving all the problems associated with telling if someone is "awake" or not in a certain time zone. Except I have two cousins, both living in the same time zone, one of which wakes up at 6am and the other wakes up at 4pm. Also, from personal experience calling people both without and with substantial time zone difference, you never know when its a good time to call someone else. They might have had a long day and took a nap. They might not be home when you think they would be. They might be engaged in an activity they don't want to be distracted from. For practical uses of synchronous communication you need to have agreements on when to call in the first place. If I'm calling someone I know, its because I know from experience when they are available, relative to my time. It does not matter if they are in Munich or Tokyo or down the street, I need to know in advance their availability for that call regardless of silly contrivances like the culturally normative sleep cycles of the region I'm calling into. Because at the end of the day, there are still tens of thousands of people in Melbourne working the night shift. |
