  //!     \n\n
  //!     It seems odd that a system snapshot implementation would need a
  //!     ProcessReaderMac, but some of the information reported about the
  //!     system depends on the process it’s being reported for. For example,
  //!     the architecture returned by GetCPUArchitecture() should be the
  //!     architecture of the process, which may be different than the native
  //!     architecture of the system: an x86_64 system can run both x86_64 and
  //!     32-bit x86 processes.
  //! \param[in] snapshot_time The time of the snapshot being taken.
  //!     \n\n
  //!     This parameter is necessary for TimeZone() to determine whether
  //!     daylight saving time was in effect at the time the snapshot was taken.
  //!     Otherwise, it would need to base its determination on the current
  //!     time, which may be different than the snapshot time for snapshots
  //!     generated around the daylight saving transition time.
