It should be noted that a few other countries have also used winter time, according to <https://en.wikipedia.org/wiki/Winter_time_(clock_lag)> (but I agree with the argument that tm_isdst is best defined as indicating whether the clocks are advanced compared to time used for the rest of the year, *not* based on whether the wording of the laws in question defines one time as standard and the other as a variation from it - there's no reason laws need to define one time as standard and the other as a variation at all). -- Joseph S.
