> he list a handful of other "smart" assistants which correctly list London UK's time...
It's only correct if that is what you secretly asked for. If I have never travelled to Europe and I am planning a trip to London, Canada then in my subjective world I would kind of be disappointed when my digital assistant told me the time of London, UK. That person would have equally zero understanding, like "WTF SIRI, why would I want to know some city somewhere I don't even know where it is located on the map when you (know) that I often go and visit Canada. Gosh you stupid idiot assistant!"
A London, Ontarian would probably expect/accept the confusion. Because if he's travelled and met international people and they asked where he's from, he would've specified ", Ontario", otherwise they would've all assumed he hails from where Sherlock Holmes lived.
