Decimated

The Economist online, of all places, posted an article on January 15 (55211) titled Decimated: What if Napoleon hadn’t abolished decimal time? The article talks about decimal time, the Egyptian calendar, decimal angle, etc.  It is not entirely accurate.  For instance, Napoleon did not abolish decimal time; it came and went before he came to power, although he did abolish the ten-day week.  And dual-face decimal clocks were not numerous in France in the 19th century, and certainly not elsewhere; almost all of them were made in the early 1790s.  It does mention Lagrange's suggestion for déci-jour and centi-jour, but he did not "try in vain" to get these as part of the metric system because France already had decimal time units.  As for the "compass", decimal angles called "grads" are actually common on calculators today, although I am not sure who uses them.  (The "gon" mentioned in the article is another word for the same thing.)  Then the article goes into hexadecimal time.  I'm not sure who uses that, either.  Unix time and Microsoft's filetime are mentioned, but not other systems, such as Microsoft Excel's decimal time and date.
