  The information I have found on Saskatchewan Daylight Time is this:

          1962-1971  Variable (each locality may have done something different) 
		     but it seems to be last Sunday in April to last Sunday
		     in October (September in 1960-1)

      1972-present?  Observed in entire province except in the far-eastern
		     part (that part is on Central Standard time all year)
		     The western part is on the last Sunday in April to
		     last Sunday in October schedule

  I don't know where the machine 'skorpio' is but I infer that it is in
the Eastern part of Saskatchewan.  Does anyone have access to an official
publication of Canada that describes DST?  Does such a publication exist?
