DTV13 — Use of 'week' vs. 'ISO week' in clause 10

  • Key: DTV13-66

  • Summary:

    DTV v1.2 changed the model of the 'week' concept to distinguish the 'ISO week' concept. Several vestigial uses of 'week' in clause 10 should be corrected:

    • In clause 10.4, in the entry for finite time scale subdivides time point kind', the Note refers to 'day of week', which should be 'ISO day of week'.
    • In the introduction to clause 10.6, the example 'week 41 day 6' should be 'ISO week of year 41 ISO day of week 6' (really?, this wording has no business use).
    • In 10.6.3, under atomic time coordinate, the example "calendar week 53" should probably be "ISO week of year 53".
    • In 10.6.3, under 'atomic time coordinate uses index', the references to 'week of year' and 'day of week' should use "ISO".
    • In clause 10.7 (Time sets), the introduction twice refers to 'week of year' and 'weekday of year', which should use "ISO"
    • Clause 10.10 makes several references to the "year of weeks" and "week-based year", which should use "ISO"

    Also, the concept 'ISO weekday of year' in clause 12 appears to mean 'day of ISO week-based year', but that characterization in so many words does not appear in the description of the time scale or the time point. The time coordinate may have the (compound) week/day form described in clause 18, or the ungainly form noted above, but the time point only has an index, and the term 'weekday' (without the solidus) is misleading.
