Bug #6246: Date::inDaylightTime() crashes Apache 2.0.55 with status 3221225477

/**
 * In 2007, daylight saving time (DST) was extended in the United States.
 * DST started on March 11, 2007, which was three weeks earlier than in
 * the past, and it ended on November 4, 2007, one week later than in years
 * past.  This results in a new DST period that is four weeks longer than in
 * previous years.
 *
 * N.B. the time at which US Summer time starts is 2.00 'Wall-Clock' Time,
 * that is, it goes forward at 2.00 in standard time, and goes back at
 * 2.00 in Summer time.  This is unlike Europe which all switches together
 * at 1.00 GMT in both directions, so that in London, for example, the
 * clocks go back at 2.00 BST (although at that exact instant, the time
 * actually becomes 1.00 GMT).
 *
 * All countries in Europe except Iceland observe DST and change on the same
 * date and time, starting on the last Sunday in March and ending on the last
 * Sunday in October. Before 1996, DST ended on the last Sunday in September
 * in most European countries; on the British Isles though, DST then ended on
 * the fourth (which some years isn't the last) Sunday in October. In the
 * West European (UTC), Central European (CET, UTC+1), and East European
 * (UTC+2) time zones the change is simultaneous: on both dates the clocks
 * are changed everywhere at 01:00 UTC, i.e. from local times of
 * 01:00/02:00/03:00 to 02:00/03:00/04:00 in March, and vice versa in October.
