-  //!     \n\n
-  //!     It seems odd that a system snapshot implementation would need a
-  //!     ProcessReader, 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.
