By default, component's timezone is the user locale timezone.
Component now offers a way to set its timezone to any supported
Intl timezone format. Please note that output values from the
component will always be converted to a UTC timezone.
Enforces a standardized approach for end consumers using the
component's API. Consumers are now required to provide a date as an
ISO string in either UTC or with a UTC offset. The support for native
Date objects has been removed to ensure consistent and reliable
behavior across all implementations. By adopting this uniform input
format, we can simplify usage and avoid potential inconsistencies in
date handling.
By introducing this utility function, we ensure that any output value
is converted back to an ISO 8601 date and time string in UTC timezone.
Overall, it harmonize and factorize the way we output
values from date picker components.
DateRangePicker aria-labels mention when a selected date range
contains today's date, which breaks the tests while ran on the
first day of the month. Avoid these tests to be flaky.
