Technically, you could create string->duration:

%%%%
#(define (string->duration str)
(let* ((parser (ly:parser-clone '()))
(music (ly:parse-string-expression parser str)))
(if (ly:duration? music) music (ly:error "Expecting duration"))))

{ b' \$(string->duration "4.") c'' \$(string->duration "8") }
%%%%

```
But it would seem better to let the parser do the work by having the function accept a ly:duration? directly. Certainly, it would be easier to use:
```
%%%%
\timeII 3 4.  % logically \time 9/8
%%%%
