Description:
------------
In PHP 5.2.3 the daylight saving start date for time zone The Netherlands is not correct for the years 1977, 1978 and 1979
This used to work correctly in PHP 4.
Below script should show 23 hours time difference for all given dates, but somehow this is not happening in 1977, 1978 and 1979.

Reproduce code:
---------------
<?
$dates = array(
  '1977-04-03',
  '1978-04-02',
  '1979-04-01',
  '1980-04-06',
  '1981-03-29',
  '1982-03-28',
  );

foreach($dates as $date)
{
  $ts1 = strtotime($date);
  $ts2 = strtotime('+1 day',$ts1);
  $diff = ($ts2-$ts1)/3600;
  echo "$date => $diff\n";
}
?>

Expected result:
----------------
1977-04-03 => 23
1978-04-02 => 23
1979-04-01 => 23
1980-04-06 => 23
1981-03-29 => 23
1982-03-28 => 23


Actual result:
--------------
1977-04-03 => 24
1978-04-02 => 24
1979-04-01 => 24
1980-04-06 => 23
1981-03-29 => 23
1982-03-28 => 23
