Is the term "Centon", as a unit of time used in Battlestar Galactica copyrighted? How would I go about finding this out? I was thinking about how people would deal with measuring time on other planets when I got to thinking about decimal time and what the units were called. Using seconds and hours would be confusing. It seemed to me that 1/100 of a day should be called a centon. At 14 minutes long, (on Earth) this would be a useful measurement for organizing the day. We already use roughly this unit, as most things happen on the half or quarter hour.
