DTV13 — Introductory text in 11.4 is confused

The first paragraph of 11.4 contains: "the names of calendar periods are
homonyms. The multiple meanings of such names can be understood by considering that each such name can refer to a set of
time points collectively, to any member of such a set, or to a unique time point on a finite time scale." And the following example says similar things.
This is confused. A term like January refers to either the time point (Gregorian month of year 1) or to one or more time periods/intervals that are instances of it. It is never a set of time points. The January of each year is a different time interval, but the same time point.
Further, the subsequent text uses Tuesday as an example, while the subclause is about Gregorian months.

Correct the wording of 11.4 to describe named time points

The cited text of 11.4 is misleading. A named time point, like any other time point designation, is usually used to refer to the corresponding time intervals. In some usages, it refers to the time point itself. The text is corrected to say this.
Considering the placement of the text in 11.4, the example of Tuesday is replaced by April.
Note also that the title of the section is inaccurate - the section is about Gregorian months of year.
