This is too hypothetical, I'm afraid.  People's pre-1970 birthdays are 
typically recorded as dates, not as POSIX time stamps.  (That's true 
even for post-1970 birthdays.)

Although it's conceivable that an application could misuse the data in 
the way you describe, it'd be pretty weird to do that, and in practice 
it's not a significant problem.  We shouldn't let hypothetical misuse 
like that get in the way of cleaning out bogus and/or out-of-scope data.
