If you want to ask the time duration and cannot insert the data-time picker, I strongly suggest you use a dropdown list, since my case shows many respondents have trouble with the input-text question with an input mask.
But you didn't show anything nor you mentionmed the version of LS that you are using.
So it is difficult to advise.
A picker is not always the best solution.
