A historical note for tzdb nerds. In 1993 when I originally wrote the entry for 
Istanbul, I naively thought that the city was primarily in Asia. But after I 
looked it up, I found that geographically the city was more European, e.g., its 
European side was larger and its ancient heart is on the Europe side. To avoid 
similar confusion by others, when I renamed my private draft's zone to 
Europe/Istanbul I added a link to the Asia name. I figured that Istanbul would 
present a unique problem in Zone naming as it is the only major city that 
straddles continental boundaries. Little did I know, eh?
