Be careful here. The real-world Gregorian calendar **does not** have leap seconds by definition. In general world usage, "UTC" is a precise timekeeping system which includes leap seconds. "Gregorian" is a system of labeling calendar dates only, and has nothing to do with length of day, or leap seconds in particular. In CF we use the calendar attribute "gregorian" in an extended sense, to identify a particular timekeeping system which combines both the real-world Gregorian calendar, and a fixed length day which does not use leap seconds. I support the general premise of this issue, all **currently defined** CF calendars have fixed length days and do not include leap seconds. If this notion is generally accepted, then it will become easier to start adding some of the more precise timekeeping systems later. -- You are receiving this because you are subscribed to this thread.
