SQL
Timestamp with Time Zone Functions
<!-- markdownlint-disable MD001 -->  
This section describes functions and operators for examining and manipulating [`TIMESTAMP WITH TIME ZONE`
(or `TIMESTAMPTZ`) values](#docs:sql:data_types:timestamp).  
Despite the name, these values do not store a time zone – just an instant like `TIMESTAMP`.
Instead, they request that the instant be binned and formatted using the current time zone.  
Time zone support is not built in but can be provided by an extension,
such as the [ICU extension](#docs:extensions:icu) that ships with DuckDB.  
In the examples below, the current time zone is presumed to be `America/Los_Angeles`
using the Gregorian calendar.
