When using date() to format date prior to Jan 1, 1970  or after Jan 19, 2038 PHP gives

Warning: unexpected error in date()

script
\\variable's byear,bmonth,bday come from user form
\\script works fine for dates between 1-1-1970 - 1-19-2038
$bdate = $byear . "-" . $bmonth . "-" . $bday ;
$dob = strtotime($bdate); 
$_SESSION['view_dob'] = date("d-m-Y",$dob);

Sorry, but the bug system is not the appropriate forum for asking
support questions. Your problem does not imply a bug in PHP itself.
For a list of more appropriate places to ask for help using PHP,
please visit http://www.php.net/support.php

Thank you for your interest in PHP.

This is a problem in Windows, not in PHP.

Reopening as a documentation problem.

I threw a quick glance on the php.net/date page last night and I couldn't find it there. If it's nere, it needs to be outlined better, or well, documented at all.

Look also www.php.net/strtotime

I'm using PHP 4.1.2 and no error on date() as got on:

<?PHP
error_reporting(E_ALL);
$time = strtotime("1850-10-10");
if ($time == -1)
{
        print "Invalid date range\n";
}
print date("d-m-Y",$time);

?>


The only error is that date will allways show the date of time = -1 on invalid range (< 1970  OR > 2038).

Is only a code bug. You should verify if $time is -1.

Please, someone check on Windows the routine I wrote.  Maybe on Windows date() return error if time is -1.

Yep,

the exact output is

Invalid date range
Warning:  unexpected error in date() in D:\Test\t.php on line 8

This bug has been fixed in CVS. You can grab a snapshot of the
CVS version at http://snaps.php.net/. In case this was a documentation 
problem, the fix will show up soon at http://www.php.net/manual/.
In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites.
Thank you for the report, and for helping us make PHP better.
