Bug description:[PATCH] Incorrect/inconsistent day of week prior to the year

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`;
   }
?>
