  I don't have any at hand, but are you saying you
  don't *EVER* want Qt to be used in:

    o Atomic clocks
    o GPS Receivers
    o Astronomical applications?

  Any of those are *CERTAINLY exposed to Leap Seconds
  several times a year (on average, though not lately).
  And, in fact, so is any application that actually
  tries to handle time in an completely-accurate fashion
  (financial trading apps, etc.)

  Perhaps you should join the movement that's trying
  to stamp-out Leap Seconds in favor of the once-
  every-900-years (or so) Leap Hour? ;-) That idea
  would certainly make life easier for us programmers!

Let's try again: please name two systems where Qt runs where the OS reports
61-second minutes.
