West Australia has made a step further to implementing DST, the lower house approved the DST bill, but to go ahead the bill must also be passed in the upper house. In the meantime rhetoric flies high, DST can save lives, the upper house should be abolished if the DST bill is not passed etc. : http://origin.theaustralian.news.com.au/story/0,20867,20682208-29277,00.html Also a sincere thanks to Chris Walton for the "Canada details", I will look into that, but it looks good at first sight, just what I needed. And an apology for the ill-thought-through question about Niger (not Nigeria!), I hadn't even seen the comment in the 'africa' file about the double use of WAT for GMT-1 and GMT+1, and besides I could have confirmed with astro.com that Shanks also agree about the GMT-1 for Niger in the period specified.
