Examples
Example #1 A timezone_transitions_get() example
<?php
$timezone = new DateTimeZone("Europe/London");
$transitions = $timezone->getTransitions();
print_r(array_slice($transitions, 0, 3));
?>

Example #2 A timezone_transitions_get() example with
timestampBegin set
<?php
$timezone = new DateTimeZone("Europe/London");
$transitions = $timezone->getTransitions(time());
print_r(array_slice($transitions, 0, 3));
?>
