Comment 31 for bug 892370

I've rebuild libtimezonemap & indicator-datetime (had to tweak a little) the code itself is fine.
But, I managed to select Scarborough, Leicester and Kettering but not London. Similarly with Beijing, I managed to click many more new cities but not Beijing.
Currently we cycle all timzeone cities in the 10x10 pixel area around the point clicked.
Maybe with offline cache we should cycle the cities by size starting with largest city in the 10x10 pixel area?!
