DTV12 — time scale differs from time scale by time offset

In clause 10.5, Figure 10.7 is titled Time Zones, and it shows a verb concept: “time scale differs from time scale by time offset”. This verb concept is in the UML model (in Time Infrastructure), but does not appear anywhere in the text of DTV v1.1. It appears to have been replaced by ‘calendar1 differs from calendar2 by time offset’ in Figure 10.8. But Figure 10.7 shows several other concepts that are defined in clause 10.5, and the definition of ‘local calendar’ refers to a time scale that “differs from the UTC day-of-hours time scale by a given time offset”, which appears to use the phantom verb concept.

The UML diagram will be realigned with the text. The definition of ‘local calendar’ and the definitions of time coordinates ‘with time offset’ are modified to use the documented verb concept ‘calendar1 differs from calendar2 by time offset’.
