The stella-maris/clock package provides an interface based on the currently proposed status of PSR20. Due to the inactivity of the PSR20 working group this is a way to already provide interoperability while still maintaining forward compatibility. When the current status of PSR20 will be released at one point in time the stella-maris/clock package will extend the PSR20 interface so that this package becomes immeadiately PSR20 compatible without any further work necessary. In the long run the stella-maris/clock package will then be marked deprecated so that people can then use the PSR20 provided implementation. Should the implementation of PSR20 change between now and a possible release then this interface will still exist and a possible implementation will need more code-changes anyhow so this interface will still provide some way of interoperability. The implementation of the PSR20 polyfill has been moved to the stella-maris/clock interface which can be implemented independentyl from PSR20 and might allow some interoperability before the working group of the FIG manages to decide upon something.
