Once/year 23 hour day 2. Once/ year 25 hour day 3. Once/ 4 years 29 day February 4. Addition of 1 second approx once per year to correct for slowing of earth rotational velocity. (note: you get about 3 months notice of this addition) The ARM says that "+" and "-" have "the conventional meaning". What is the convention in these cases? If I perform a +/- on the day before/after one of the above 4 events what is "the convention"? If I ask package calendar for the time is it required to always give the correct answer? The ARM seems silent on time accuracy so what are your requirements? (I heard on radio news this fall that Amtrak has it's trains stop for one hour to maintain schedule when clocks are set back. I don't know if this is true or not and they didn't say how they handle the setting ahead of the clocks in the spring.) regards, sam harbaugh --------------------- ------
