Just out of curiosity, are there any IALs that do not allow the same preposition-type word to be used for both space and time? For example, a locational preposition is also often used for time, as in "He lived IN the 17th century." And also, words like "before" are often used for both space 'he stood before the house" and time "he died before his wife did". And there are usages like "the days are long". Are there people who object to using terms like that?
