Actually, timezones are to great extent already mapped, you only have to find a better way to extract the data, instead of creating new relations. There might still be administrative relations that doesn’t have timezone tag set making the timezone data incomplete, but this is not a reason to create new relations, but rather add the missing data in existing relations.
