  Because even if I'm not doing timekeeping to that
  granularity, I may be processing time records
  originating elsewhere that have that sort of
  fine-grained granularity.

  For example, the timestamps recorded by the Linux
  Kernel are at microsecond granularities and the
  timestamps recorded by my USB tracing tool are
  at nanosecond granularities.

  It would be nice if the Qt time-processing functions
  can make it easy for me to process all of those.

  (I'm not the person making the request but) I think
  what I'd want is assurances that Qt has been tested
  in the presence of Leap Seconds and does reasonable
  things with those exceptional time values. That is,
  nothing should SegFault, time formatters should
  display 23:59:60, delta time calculations should
  work accurately, and so forth.

Why? I can see the point, but really?

Already supported.

What's the usecase?

Please point me to two systems where this is used.
