Change and add: <s>- the solar-day is a commonly used unit of measurement</s>
<u>- TAI and parallel time scales have been defined so that in modern times the difference between an atomic day and a solar day is not perceptible without the aid of timepieces. Popular acceptance of atomic days as a basis of the civil calendar and the corresponding deprecation of the solar day will not be truly tested until the difference between the two is perceptible without a timepiece.</u>
- the SI second is part of a coherent system of units and redefinition of the second would
disturb the definition of most other units _______________________________________________ LEAPSECS mailing list [email protected] http://six.pairlist.net/mailman/listinfo/leapsecs
