Why does the alarm clock snooze button give you nine extra minutes, not ten?

edit: It sounds like the first alarm clock with a snooze might have been synchronous so maybe it's worth thinking more about that :)

It's a bummer the Wikipedia article for Alarm clocks cites the straight dope article which links to some suggestive information that is totally missing now. It's too bad that Wikipedia doesn't store source information that is important for verifying the statements in articles in case the linked source disappears (or does it?)

originally, and probably wrong:

Yeah, some clocks used this, but I don't think it was most clocks and unless the first clock with a snooze functionality was this type, it doesn't give any more insight into why 9 minutes was chosen.

Good reason to donate to www.archive.org :) It's probably accessible there, and the citation should include a date you can rewind to. Not that that's ideal, but it's at least verifiable, and probably available now if not forever.
