I view this incident with some relief. A mistake was noticed and addressed relatively quickly. In a classic experiment by Rotter, people continued to believe the time given by a clock when it was running at only 25% its normal rate. Rotter, George. 1969. Clock-Speed as an Independent

Re: [LEAPSECS] drawing the battle lines

I'm still puzzled at the reasons for stating that UT1 should not be considered as a time scale in this recommendation. How does that serve this recommendation? This is a bit of a different question from evaluating UT1 as a time scale. Instead, it is a question about the reasons why the

Re: [LEAPSECS] Calendars count days - clocks divide them up

The day is panculturally recognized as a time reference, but many cultures are not concerned with the day as a uniform unit of duration. Instead, days can vary in length (like months and years), and it is not a problem. Very few cultures have defined the concept of day both in relationship to

Re: [LEAPSECS] LEAPSECS Digest, Vol 88, Issue 31

Because Roman reckoning did not include a zero, the leap year in Julius Caesar's calendar was miscalculated. They instituted a leap year ever 3 years rather than every four because the 1st and 4th year of the cycle were considered the same (a fence post error). Augustus corrected this error

Re: [LEAPSECS] Definition of Standard time - Brooks Harris

There are many timekeeping traditions across many cultures. For most, the move to mean time and the implementation of hours of uniform length were the breaks from tradition. A good demonstration of this is Japanese clocks before and after 1873. During Pope Gregory's life, there were many
