### 3224. `zoned_time` constructor from `TimeZonePtr` does not specify initialization of `tp_`

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 27.11.7.2 [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_`.
