[plt-scheme] Re: FrTime niggle

I have traced the reason for the failure:

> (module mod:integer? mzscheme (provide integer?))
> (require mod:integer?)
> (integer? seconds)
#f
> (integer? (modulo seconds 10))
#f

And iota has the line
	  (check-arg integer? count 'iota)
That generates this error.


ifconfig.
