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.
