-  // On all three main platforms that we target (GNU/Linux, Windows (both
-  // VC++ and GCC/MinGW64), and MacOS X) with recent C++ runtimes,
-  // system_clock has nanoseconds resolution and counts from the UNIX
-  // epoch. The latter is important since struct stat also returns times
-  // based on UNIX epoch.
-  //
-  // The underlying type for nanoseconds duration is signed integer type
-  // of at least 64 bits (currently int64_t). Because it is signed, we
-  // will overflow in year 2262 but by then the underlying type will
-  // most likely have changed to something larger than 64-bit.
-  //
-  // So to support other platforms that could possibly use a different
-  // system_clock resolutions (e.g., microseconds), we actually not going
-  // to assume anywhere (except perhaps timestamp.cxx) that we are dealing
-  // with nanoseconds or the 64-bit underlying type.
