/**
 *  @defgroup SuperCoreTimeStamp Score Timestamp
 *
 *  @ingroup RTEMSScore
 *
 *  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.
