/**
* @defgroup RTEMSScoreTimestamp Timestamp Handler
*
* @ingroup RTEMSScore
*
* @brief This group contains the Timestamp Handler implementation.
*
* This handler encapsulates functionality related to manipulating
* SuperCore Timestamps. SuperCore Timestamps may be used to
* represent time of day, uptime, or intervals.
*
* The key attribute of the SuperCore Timestamp handler is that it
* is a completely opaque handler. There can be multiple implementations
* of the required functionality and with a recompile, RTEMS can use
* any implementation. It is intended to be a simple wrapper.
*
* This handler can be implemented as either struct timespec or
* unsigned64 bit numbers. The use of a wrapper class allows the
* the implementation of timestamps to change on a per architecture
* basis. This is an important option as the performance of this
* handler is critical.
