"The biggest hurdle in Japan to putting daylight saving time in place is the cost and workload required to adjust computer systems.

Let’s send ‘em a bill. ;-)
I rather imagine the professor has a point. Yeah, code that uses tzdb would be easy to update. But Japan is likely chock-full of locally grown code that has never had to cope with any situation other than "JST = UTC+9", and probably hasn't got any generality whatsoever about its timestamp handling. regards, tom lane
