An annoying thing about Japan is the kind of reverse daylight savings time used here. I don't know exactly why this is, but it gets light at 3:57 AM. That wouldn't be so bad, but it is dark by 7 or 7:30. If it gets dark an hour after 6 PM, shouldn't it get light an hour before 6 AM? We are not far out of the center of the time zone, either, not like all of China operating on the same time zone. Solar noon is at 11:43. I guess my astronomy has got a bit rusty here where we see only a handful of stars most of the time. I wish there were Daylight Savings Time here but it still has a bad reputation from the postwar era where it was used to squeeze more work out of construction workers who typically took off when it got too dark to work. I think it is still opposed by unions and has no proponents as far as I have heard.
