In practice, it is impossible. struct tm exists in binary form in thousands of places that can't be updated. If it weren't for the fact that tm_gmtoff and tm_zone already exist in essentially every implementation, and have done for years, there's no way they could have been added to the standard (and is why it took so long).

So we're presumably ruling out AIX and Solaris, for example, as implementations to count in the set of "essentially every implementation".
