Here is the latest incarnation.

With respect, it's hardly the latest, since I first saw that page a couple of years ago. I have seen other examples of "metric time" since then, but have not thought them worthy of mention here. For instance, some fellow in Iceland created a Decimal Time Project at http://dada.is/DTP/ , which counts the days since the metric decree of April 7, 1795, similar to Julian Day numbers, and defines a unit named Dies as equal to one day, with metric prefixes, e.g. KiloDies, HectoDies, DekaDies, deciDies, centiDies, milliDies and microDies. This, at least, is more "metric" than most so-called "metric time" proposals. However, others have, over the years, also proposed adding metric prefixes to the day unit.

Of course, "metric clocks" which divide the day into ten "hours", hours into one hundred "minutes", etc., are usually recreating French revolutionary decimal time. This was never a part of the metric system, but was introduced at about the same time. The 1795 decree, which defined the units metre, are, stere, litre and gramme, and the metric prefixes, did not include a unit for time, and ironically suspended the mandatory use of decimal time, which had been enacted nearly two years before.

About a century later, the French, through an official committee headed by Henri Poincaré, again attempted to decimalize civil time and proposed the standard hour as the metric unit, but it also did not get very far. By this time, scientists were already using the second as part of the metric system.
