Nice try, but that's not how it's done.  They put in an extra second in the 
last minute of the day.
  23:59:59
  23:59:60
  00:00:00

Humm.  Isn't that backwards.  Don't you want to remove a pulse?  Inserting a 
leap-second is equivalent to stopping the clock for a tick.

I suppose you could setup a microprocessor that listened to the text and mask 
out a pulse at the right time.

That would delay the PPS pulse by the prop time through an AND gate so we 
could come up with time-nut level schemes to fix that.

Or you could just wait for the next leap second and stick your finger in the 
works at the right time.
