Just curious. The contact for find-seconds parameter second (integer-in 0 61)
instead of (integer-in 0 59). [1]
The Java definition of a Date [2] states "the values 60 and 61 occur only for
leap seconds and even then only in Java implementations that actually track
leap seconds correctly," which made me wonder if the values 60 or 61 were
actually used by Racket. According to [3], we've had one leap second at the
end of 2005 and 2008. Does any PLT Scheme or Racket code actually track or use
those leap seconds? I guess if I were using Racket to fire reverse thrusters
for re-entry on the space shuttle, I might want to know, since the shuttle
moves along at six miles per second.
