Well, and it's further complicated by the context of what's being asked. Coming from Waterloo Region, if I ask what time it is in London, I almost certainly mean in England. But if I ask for directions to get to London, I probably mean the one that's a few hours away by car. So it's not as simple as just fitting these queries into generic templates and sending all instances of $LOCATION to a common geocoder.
