"local time" in the function "ionmodel" #546

I'm confused why not use "local time" in the function "ionmodel" according to the code as bellow:

/ local time (s) / tt=43200.0lam+time2gpst(t,&week); tt-=floor(tt/86400.0)86400.0; / 0<=tt<86400 /

It seems like the time2gpst outputs UTC time.

I think your suggestion is better. But IS-GPS defines the model by using GPS time (IS-GPS-200K, Figure 20-4) and there is no difference within the accuracy of the model.
