Can anyone explain why the following code generates the
above warning?

secsperyear = 365.25*24*60*60;
deltat = secsperyear/Nt;
seasonaltime = n deltat;


interpFunc[seasonaltime1]; (* no domain warning message *)
interpFunc[seasonaltime]; (* this DOES produce domain-warning message?!
yet SameQ[seasonaltime,seasonaltime1] is True?! *)

I am totally mystified!  Is this a bug in InterpolatingFunction?

Thanks for any advice or explanations.
