Probably not a good time to propose decitime, I guess. (No pun intended.) Day is the basic measure. Deciday = day/10. (=~ 2.4 hour) Centiday = day/100 Either could be used in place of the old fashioned hour. Milliday = day/1000 (=~ 84 seconds) Milliday seems like a good replacement for the traditional minute. Centimilliday to replace seconds? It's a but unwieldy but could be abbreviated as cmd (similar to the commonly used 'sec.') Years are a little troublesome. However with sufficient energy input a Kiloyear could be made to be 3 years. With sufficient precision (and perhaps occasional correction) it could resolve that leap year and occasional leap second issue. There would be some ramifications. For example the Newton is defined in terms of seconds so there are some units beyond pure time that would also require revision. Let's get rid of this madness of 24 hours, 60 minutes and 60 seconds. And 365.2425 days was just plain wrong from day 1.
