Daylight savings, the brain and learning

I have a bit of a thing about brains and I have posted before (on my other blog) about young brains, sleep and learning.
Some schools start later in the day specifically to address the issue that the majority of children seem to become “night owls” during adolescence. A recent report presented at the 2008 Australasian Sleep Association Conference suggests that parents need more guidance in setting bedtime rules to assist teens with the morning wakeup. There are simple (but tough to implement!) strategies, the most important of which concerns light. Reduce light exposure in preparation for sleep and increase light for waking.
So where does daylight savings fit in? Effectively having the sun rise and set an hour later each day seems to be counter-intuitive to what we know about young people and their brains. Am I the only one that thinks daylight savings disadvantages adolescents?
