Earlier this week Mainichi Japan published an article describing some criticism
of reintroducing DST to Japan. My favorite quote was this one, abut the time and
cost to reprogram computers:
"The biggest hurdle in Japan to putting daylight saving time in place is the
cost and workload required to adjust computer systems. Professor Tetsutaro
Uehara of Ritsumeikan University, a specialist in information systems, estimates
that it would take about four years and hundreds of billions of yen to do just that.
"'Japan is a country with advanced information technology systems, and computers
with timing functions are used everywhere. Many are programmed with Japan time
based on the international standard time,' pointed out Uehara. 'Software would
have to be rewritten to introduce summer time. Such work would take about four
years and cost hundreds of billions of yen. It is crazy to attempt to put it in
place by the 2020 Games,' said the bewildered professor."

critics. The Mainichi. 2018-08-12.
