Agreed. But I didn’t say it was always a bad idea, just never a good one. :) Seeding with something like a timestamp gives you results that are neither repeatable nor truly unguessable, and I can’t think of any situation where that would be a benefit. Especially when it’s more work than just calling srandomdev(). Besides, people tend to search for snippets of existing code and paste them into new code, and it would be sad if code like the above got moved from, say, a game to, say, a password generator. —Jens
