R help - Jul 2008 - S 3 generic method consistency warning please help

I would like to include this in a package.  The S3 methods on R CMD check
says
* checking S3 generic/method consistency ... WARNING
window:
  function(x, ...)
window.chron:
  function(data, day1, hour1, day2, hour2, ...)

See section 'Generic functions and methods' of the 'Writing R
Extensions'
manual.

I have looked and can not figure it out.  This function is for convience.
What can I do to fix this?  This is the first time I have tried this, so be
easy, and explain it to to me and I will try and understand.  I'm tired
maybe that's it


window.chron <- function(data, day1,hour1,day2,hour2){

window(data, start=chron(day1, hour1), end=chron(day2, hour2))

}

#take a one day subset of a longer series
t1 <- chron("1/1/2006", "00:00:00")
t2 <- chron("1/31/2006", "23:45:00")
deltat <- times("00:15:00")
tt <- seq(t1, t2, by = times("00:15:00"))
t <- rnorm(2976)
z <- zoo(t, tt)
f <- window.chron(z, "1/20/06", "00:00:00",
"1/20/06", "23:45:00")

little or so large that all they really do for us is puff us up and make us
feel like gods. We are mammals, and have not exhausted the annoying little
problems of being mammals.

If you look at the generic formal arguments they look like this
> args(window)
function (x, ...)


but your window method does not start with an argument called x so
its inconsistent with its generic.

Mac OS X 10.5.4
R 2.7.1
the function works fine when I use it in a regular session.  I can post
source code and the like if it is necessary to diagnose the problem.  If
ya'll need anything else just tell me.
thanks
