behaviour of unix timestamp functions for dates
before 1.1.1970 is simply undefined and depends 
on the system *and* c library implementation you
use

so stay away from undefined value ranges :)

What's the offical suggestion for getting UNIX timestamps for dates < 1970? Or is it not allowed to use them this way?

BTW: The offical PHP docs say, that dates between 1902 and 2037 are _allowed_. But you say "so stay away from undefined value ranges"!? Very strange. 

Can you explain that to the users/developers community?

My ISP is using a new release of glibc and now mktime strtotime are not working for dates prior to 1970. I need to be able to add subtract a day from dates between now and before 1870.... anybody ?

ie http://www.boxrec.com/date_search.php I need to generate the dates either side of the search date for the forward / backward links.
