The time functions defined by the XACML core specification [XACML3] have limited utility when used in widely distributed and replicated environments where times are presented with various, different time zones.

This has caused issues with Guard policies used in Control Loops that utilize time ranges.

As an ONAP Developer, I want to add new Time Extensions to the open source xacml project so that ONAP XACML PDP can utilize the new time extensions in anticipation of dynamic distributed environments in which control loops are running.
