The clock/timer APIs are not application facing APIs, however, similar to arch_ and a few other APIs they are available to implement drivers and add support for new hardware and are documented and available to be used outside of the clock/kernel subsystems. Remove the leading z_ and provide them as clock_* APIs for someone writing a new timer driver to use. Signed-off-by: Anas Nashif <anas.nashif@intel.com>
