Detailed Description

Abstract class representing the interface to an OBS Clock Component that can provide timing-related information and services to the application.

OBS Clock Components can provide two types of timing information and one service. The timing information are: the on-board time and the on-board cycle. The service is the timing synchronization service.

The on-board time is a time measurement provided by some external source. The on-board cycle assumes that the application is running cyclically and it represents the number of cycle from some arbitrary point (for instance, the time of creation of the OBS clock component, or the time it was last reset).

The timing synchronization service is an application-dependent service to synchronize the on-board time maintained by the OBS clock component.

Todo:

create a PUSObsClock class derived from this class to implement PUS-specific timing services

spilt the setTime method into two setter methods
