You are (incorrectly) converting the variable gettime into a string ('gettime').
Instead, use a bind variable:
execute immediate
'select count(*) from test where ((testdate - :gtime) * 24) <= 4' into v_count using gettime; |

I'm not sure where you're trying to go with this query. You have not aliased the inline view or its column (count(*)), and so its value isn't reflected in your select statement.
To answer your question though, your entire query would have to be NDS, not just the inline view part.
