Date Error

The following code using PHP 4.02, Apache 1.3.14, Mac OS X PB: <?php for ($i = 1990; $i <= 2010; $i++) { $lastday = mktime (0,0,0,12,0,$i); echo "Last day in Nov $i is: " . date("M d", $lastday) . "<br>"; } ?> Produces the following incorrect output: Last day in Nov 1990 is: Nov 30 Last day in Nov 1991 is: Nov 30 Last day in Nov 1992 is: Nov 29 Last day in Nov 1993 is: Dec 01 Last day in Nov 1994 is: Nov 30 Last day in Nov 1995 is: Nov 30 Last day in Nov 1996 is: Nov 29 Last day in Nov 1997 is: Dec 01 Last day in Nov 1998 is: Nov 30 Last day in Nov 1999 is: Nov 30 Last day in Nov 2000 is: Nov 29 Last day in Nov 2001 is: Dec 01 Last day in Nov 2002 is: Nov 30 Last day in Nov 2003 is: Nov 30 Last day in Nov 2004 is: Nov 29 Last day in Nov 2005 is: Dec 01 Last day in Nov 2006 is: Nov 30 Last day in Nov 2007 is: Nov 30 Last day in Nov 2008 is: Nov 29 Last day in Nov 2009 is: Dec 01 Last day in Nov 2010 is: Nov 30 While the same code on PHP 3.016 produces correct output. Any ideas or workarounds? ---------------------------- Thank you.
