If you see negative times (e.g., -00:00:00,006 ), either your original had very early subtitles or you subtracted too much — but 20 sec from start is fine unless file begins under 20 sec.
If your subtitles display correctly at the beginning of the video but fall completely out of sync by the mark, you are dealing with a frame rate mismatch or progressive timeline drift. This occurs when a subtitle file configured for 23.976 fps (frames per second) is played over a video running at 24 fps or 29.97 fps.
