Discussion:

The zoned_time(TimeZonePtr z) does not specify how the tp_ sub-element is initialized. It should be consistent with zoned_time(string_view) that default initializes tp_.

Proposed resolution:

This wording is relative to N4820.

  1. Modify 29.11.7.2 [time.zone.zonedtime.ctor] as indicated:

    explicit zoned_time(TimeZonePtr z);
    

    -5- Requires: z refers to a time zone.

    -6- Effects: Constructs a zoned_time by initializing zone_ with std::move(z) and default constructing tp_.
