This remains experimental in Qt 6.9 as some standard library implementations do not faithfully represent the IANA data for timezones. + + \section1 QSpan - a Qt version of \c {std::span} + + The \l {https://en.cppreference.com/w/cpp/container/span}{std::span} class + template is an addition to the standard library that provides a uniform + way to access a contiguous portion of any contiguous container. + + Using \c {std::span} in the public APIs of Qt could provide significant + advantages.
