Try instead using a syntax something like this, to let the compiler
know which arguments match the array arguments it knows about:

       status   = nf90_put_var (gio_files(ifile)%fileID, &
                               timevid,                 &
                               the_time,                &
                               start = (/ start_time /), &
                               count = (/ count_time /) )

If that doesn't work, you may also have to put the_time in similar
array quotes (I don't know what Fortran calls them):

       status   = nf90_put_var (gio_files(ifile)%fileID, &
                               timevid,                  &
                               (/ the_time /),           &
                               start = (/ start_time /), &
                               count = (/ count_time /) )

This worked on a modification of one of our netCDF-4 examples in the
source distribution:

  examples/F90/nc4_pres_temp_4D_wr.f90

to make it look like the program you have described.

I've attached the modified example, which seems to compile and work
fine for netCDF-4 using an f95 compiler.
