Order of methods called matters for dependency reasons.

happen when using threads where one thread calls a locale-dependent
function while another thread changes the locale while the function in
the other thread is still running. Proper coding would call for
locks to prevent changing the locale while locale-dependent code is
running. The check here is done in case someone does not think about
doing this.
Only other possible issue is if someone changed the timezone and did
not call tz.tzset . That is an issue for the programmer, though,
