It’s that time of year, and I never knew if Japan had DST. So, having been reminded of the issue by User Friendly, I did a web search and found that Japan does not follow daylight saving time. You learn something new every day, and today one of the things I learned is that in Antarctica there are three time zones observed: Chile, GMT-3 and New Zealand. The Chilean and New Zealand zones observe their relative DST settings, but the British base at Rothera maintains GMT-3 all year. So, when the UK “springs forward” I’ll only be eight hours ahead of the UK.
