1. It will take 5 days to manufacture them
  2. It took us half an hour to wait

If I want to change the sentences above to noun phrases, time's possessive form, can I write them as below, thanks in advance.

  1. 5 days' production
  2. Half an hour's waiting
  • I am not sure but is this you are looking for? the production for 5 days, or 5 days for production; the waiting for half an hour, or half an hour for waiting; – Antonio Aug 28 '19 at 12:53
  • I want to know if the possessive form can be used for the same meaning as I write above,thanks. – sinbadsuuny Aug 28 '19 at 12:57

Your examples are correct.

Depending on the context, you might change the phrasing.

"Five days' production" would often be phrased "Five days' production time" and "Half-hour's waiting" would often be phrased "a half-hour's wait." But again, this will depend on the rest of the sentence.
