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.
