///   0 will always be at least "30 days ago".  Also, negative numbers
///   will never be returned.
/// - Wraparound / overflow is not a practical concern.
///
/// If you are running under the debugger and stop the process, the clock
/// might not advance the full wall clock time that has elapsed between
/// calls.  If the process is not blocked from normal operation, the
/// timestamp values will track wall clock time, even if you don't call
/// the function frequently.

/// it to values obtained on another computer, or other runs of the same process.
