Return Values

One of the constants IntlCalendar::WALLTIME_FIRST, IntlCalendar::WALLTIME_LAST or IntlCalendar::WALLTIME_NEXT_VALID.

Examples

Example #1 IntlCalendar::getSkippedWallTimeOption

<?php
ini_set
('date.timezone''Europe/Lisbon');
ini_set('intl.default_locale''en_US');
ini_set('intl.error_level'E_WARNING);

//On March 31st at 0100, the clock goes forward 1 hour and from GMT+00 to GMT+01
$cal = new IntlGregorianCalendar(2013/* March */31130);

var_dump(
    
$cal->isLenient(),               // true
    
$cal->getSkippedWalltimeOption() // 0 WALLTIME_LAST
);

$formatter IntlDateFormatter::create(
    
NULL,
    
IntlDateFormatter::FULL,
    
IntlDateFormatter::FULL,
    
'UTC'
);
var_dump($formatter->format($cal->getTime() / 1000));

$cal->setSkippedWallTimeOption(IntlCalendar::WALLTIME_FIRST);
var_dump($cal->getSkippedWalltimeOption()); // 1 WALLTIME_FIRST
$cal->set(IntlCalendar::FIELD_HOUR_OF_DAY1);

var_dump($formatter->format($cal->getTime() / 1000));

$cal->setSkippedWallTimeOption(IntlCalendar::WALLTIME_NEXT_VALID);
var_dump($cal->getSkippedWalltimeOption()); // 2 WALLTIME_NEXT_VALID
$cal->set(IntlCalendar::FIELD_HOUR_OF_DAY1);

var_dump($formatter->format($cal->getTime() / 1000));

The above example will output:

bool(true)
int(0)
string(40) "Sunday, March 31, 2013 at 1:30:00 AM GMT"
int(1)
string(41) "Sunday, March 31, 2013 at 12:30:00 AM GMT"
