        <pre>The TimeValue::toPosixTime() and TimeValue::toWin32Time() incorrectly convert
the timestamp value to Posix/Win32 ticks.

The two functions currently read as follows:

    /// Converts the TimeValue into the corresponding number of "ticks" for
    /// Posix, correcting for the difference in Posix zero time.
    /// @brief Convert to unix time (100 nanoseconds since 12:00:00a Jan
1,1970)
    uint64_t toPosixTime() const {
      uint64_t result = seconds_ - PosixZeroTime.seconds_;
      result += nanos_ / NANOSECONDS_PER_POSIX_TICK;
      return result;
    }

    /// Converts the TimeValue into the corresponding number of "ticks" for
    /// Win32 platforms, correcting for the difference in Win32 zero time.
    /// @brief Convert to windows time (seconds since 12:00:00a Jan 1, 1601)
    uint64_t toWin32Time() const {
      uint64_t result = seconds_ - Win32ZeroTime.seconds_;
      result += nanos_ / NANOSECONDS_PER_WIN32_TICK;
      return result;
    }

There is no unit conversion performed when computing the seconds part.  The
values of NANOSECONDS_PER_POSIX_TICK and NANOSECONDS_PER_WIN32_TICK also seem
to be wrong (they're both 100).</pre>
