Your time dimension is set to the first time of the first file, but
your second file is not defined at that time.

An excerpt from the doc page http://iges.org/grads/gadoc/variable.html :
"When you specify a dimension in grid units, GrADS always converts it
to world coordinates. In general, this conversion is done using the
scaling of the default file. The only exception to this rule is in
this case, when a grid coordinate (x, y, z, t, or e) is supplied
within a dimexpr as part of a variable specification. In the case of
this special exception, the conversion is done using the scaling for
the file that variable is to be taken from."

ga-> d cp.2(t=1)

should give you the display you're looking for.

Your life would be a lot easier if you aggregate these data files
together into a single using templating.
