Ehhh... works fine here! Dunno what's wrong. Don't you do anything
else within your code that can f#ck up the date? I have absolutely
no problems with the piece of code you've send. I went through
almost a complete year using the link it produces. No prob at all.

Btw; you can just use:

        $yesternews = date("Y-m-d", mktime(0,0,0,$regs[2],$regs[3]-1,$regs[1]));

PHP will make sure it produces a correct date. Then you don't have
to works with timestamps and seconds and stuff. Just let PHP do all
the work. That's what it's designed for :)
