As stated that is not possible.  Each major tic generates a grid
line whether or not it has a visible label associated with it.

You might be able to construct a command that adds tics only
at the time labels, but then you would have neither grid line
nor tic marks at the other points.

Hmm.  I suppose if the other points are evenly spaced you might
be able to add them back as minor tics using the "set xmtics"
command.
