DTV11 — Clause 8.3.2 dependency upon clause 10.2

Title: Clause 8.3.2 dependency upon clause 10.2
Source: Mark H. Linehan, IBM Research, mlinehan@us.ibm.com
Summary:
The definitions of several standard time units that are defined in clause 8.3.2 are dependent upon "period" concepts that are defined in clause 10.2. Specifically:

The Definition of day in 8.3.2 references calendar day, which is in 10.2
The Definition of year in 8.3.2 references calendar year, in 10.2
The Definition of month in 8.3.2 references calendar month, in 10.2
The Definition of week in 8.3.2 references calendar week, in 10.2

This violates the Vocabulary structure shown in figure 7.3

It is not necessary for any of these units to make definitive references to the concepts in clause 10.2. Two of these units are taken to be precise multiples of ‘day’. The other two are nominal units that approximate the time intervals of astronomical events. Those same intervals are cited in the definitions in clause 10.2. They can be used in both places, so that (v1.0) clause 8.4.2 does not definitively reference clause 10.
