Method Detail

__construct() ¶ public

__construct(Cake\Chronos\ChronosDate|DateTimeInterface|string $time = 'now', DateTimeZone|string|null $timezone = null)

Create a new Immutable Date instance.

Dates do not have time or timezone components exposed. Internally ChronosDate wraps a PHP DateTimeImmutable but limits modifications to only those that operate on day values.

By default dates will be calculated from the server's default timezone. You can use the timezone parameter to use a different timezone. Timezones are used when parsing relative date expressions like today and yesterday but do not participate in parsing values like 2022-01-01.

Parameters

Cake\Chronos\ChronosDate|DateTimeInterface|string $time optional: Fixed or relative time
DateTimeZone|string|null $timezone optional: The time zone used for 'now'

__debugInfo() ¶ public

__debugInfo(): array

Return properties for debugging.

Returns

array

__get() ¶ public

__get(string $name): string|float|int|bool

Get a part of the object

Parameters

string $name: The property name to read.

Returns

string|float|int|bool

Throws

InvalidArgumentException

__isset() ¶ public

__isset(string $name): bool

Parameters

string $name: The property name to check.

Returns

Returns a formatted string specified by setToStringFormat() or the default DEFAULT_TO_STRING_FORMAT format.

Returns

string

_formatObject() ¶ protected

_formatObject(DateTimeInterface $date, array<int>|string $format, string|null $locale): string

Returns a translated and localized date string. Implements what IntlDateFormatter::formatObject() is in PHP 5.5+

Parameters

DateTimeInterface $date: Date.
array<int>|string $format: Format.
string|null $locale: The locale name in which the date should be displayed.

Returns

string

_parseDateTime() ¶ protected static

_parseDateTime(string $time, array<int>|string $format, DateTimeZone|string|null $tz = null): static|null

Returns a new Time object after parsing the provided time string based on the passed or configured date time format. This method is locale dependent, Any string that is passed to this function will be interpreted as a locale dependent string.

Unlike DateTime, the time zone of the returned instance is always converted to $tz (default time zone if null) even if the $time string specified a time zone. This is a limitation of IntlDateFormatter.

If it was impossible to parse the provided time, null will be returned.

Example:

 $time = Time::parseDateTime('10/13/2013 12:54am');
 $time = Time::parseDateTime('13 Oct, 2013 13:54', 'dd MMM, y H:mm');
 $time = Time::parseDateTime('10/10/2015', [IntlDateFormatter::SHORT, IntlDateFormatter::NONE]);

Parameters

i18nFormat() ¶ public

i18nFormat(string|int|null $format = null, string|null $locale = null): string|int

Returns a formatted string for this time object using the preferred format and language for the specified locale.

It is possible to specify the desired format for the string to be displayed. You can either pass IntlDateFormatter constants as the first argument of this function, or pass a full ICU date formatting string as specified in the following resource: https://unicode-org.github.io/icu/userguide/format_parse/datetime/#datetime-format-syntax.

Examples

$date = new Date('2014-04-20');
$date->i18nFormat(); // outputs '4/20/14' for the en-US locale
$date->i18nFormat(\IntlDateFormatter::FULL); // Use the full date format
$date->i18nFormat('yyyy-MM-dd'); // outputs '2014-04-20'

You can control the default format used through Date::setToStringFormat().

You can read about the available IntlDateFormatter constants at https://secure.php.net/manual/en/class.intldateformatter.php

Should you need to use a different locale for displaying this time object, pass a locale string as the third parameter to this function.

Examples

$date = new Date('2014-04-20');
$time->i18nFormat(null, 'de-DE');
$time->i18nFormat(\IntlDateFormatter::FULL, 'de-DE');

You can control the default locale used through Date::setDefaultLocale(). If empty, the default will be taken from the intl.default_locale ini config.
