Daylight hours

I think I've commented recently about the fact that it is getting really hot here lately. Summer is definately here. The heat in the middle of the day is pretty unbearable, but I am finding it difficult to avoid that time of the day. Why not garden in the evenings when it is nice and cool I hear you saying. It is summer, the days are long are they not?
If you are thinking that you would be correct, but... here in Japan they have no daylight savings, so the current hours of daylight are from 5:03am to 7:22pm. That's right - it is dark here by 7:30pm even in the middle of summer.... great for barbeques! Of course I could get up at 5am and do a couple of hours work before I get the kids ready for school, but......
