    Yes, negative leap seconds are possible -- on paper. But I hope we
    never have to do that, because I suspect many programmers have not
    allowed for such a thing!
    
    I like this leap second page at the U.S. Naval Observatory:
    http://tycho.usno.navy.mil/leapsec.html
    The links lead you into all sorts of interesting information.
    
    
    Here's a large page full of links on the history and future of the
    leap second. There's even a leap second mailing list.
