I have regularly read that all it takes is 15-30 minutes of direct sun exposure per day to generate the RDA of vitamin D. Is that inaccurate (as someone who slathers his kids with sunscreen I would really like to know)?

Here's a nifty calculator that tells you vitamin D values for exposure times taking season and latitude into account.

I don't know the answer to that. However, assuming you are correct, I live in a country where direct sun exposure is a rare commodity even in summer, so the recommendation to my parents could still make sense then.
