Description:
------------
PHP timelib calculates the day of the week incorrectly for dates prior to the 1st of January 1600.
Test script:
---------------
<?php
ini_set('date.timezone', 'UTC');
print "Date PHP OS\n";
print "---------- --- ---\n";
$dates = array('1599-12-30', '1599-12-31', '1600-01-01',
'1600-01-02');
foreach ($dates as $date) {
print strftime(
"%Y-%m-%d %a ",
strtotime($date)
) . env TZ=UTC date --date=$date +%a;
}
?>
Expected result:
----------------
Date PHP OS
---------- --- ---
1599-12-30 Thu Thu
1599-12-31 Fri Fri
1600-01-01 Sat Sat
1600-01-02 Sun Sun
Actual result:
--------------
Date PHP OS
---------- --- ---
1599-12-30 Fri Thu
1599-12-31 Sat Fri
1600-01-01 Sat Sat
1600-01-02 Sun Sun
