The argument here though, is convenience rather than timezones. To reference the premise in the article: What if Uncle Steve in Melbourne is a baker or a night security guard? Then 4:25am would absolutely be a fine time to call him. All these machinations to find a mutually convenient time. Heck, I have trouble finding a mutually convenient time to arrange a sit down chat with my wife, and we both live (and work) in the same house in the same time zone. Meetings almost always means at least one party has to compromise their existing schedule and suffer some level of inconvenience.
