The 12 x 30 might be inspired by either the French Republican Calendar (see DateTime::Calendar::FrenchRevolutionary) or its ancient model, the Egyptian calendar. Part of the French Revolution / French Republic was the idea do make everything measurable in decimal. A week of ten days instead of seven (thus completely decoupling the week from the phases of the moon), decimal time, and the rather successful metric system. It is interesting that - in the long run - people accepted the metric system for almost everything but date and time. The calendar is a complex beast, and it has to be, as long as it shall be coupled to astronimical year. The only reason I can see why people did not accept the system of 10n "decimal seconds" per day is that it would have required replacing all existing clocks. People all across France, Europe and many parts of the world were used to find and use different currencies and units of measurement for distances, areas, volumes, weights, and so on whenever they crossed a border or even moved from one town to another. But they all used the same system of 2x 12 hours, 60 min / h, 60 sec / min. The metric system was "just another set" of units, but the decimal time was something unusual and new. And it would have required a lot of work and money to make daytime decimal. It would have been the right time, and it would have made modern clocks and software handling daytime a little bit simpler. But I doubt we will change to a different clock system before we get off this planet. In that respect (and not only in that respect), A Deepness in the Sky is visionary:
