/**
 * DateValidator verifies if the attribute represents a date, time or datetime in a proper [[format]].
 *
 * It can also parse internationalized dates in a specific [[locale]] like e.g. `12 мая 2014` when [[format]]
 * is configured to use a time pattern in ICU format.
 *
 * It is further possible to limit the date within a certain range using [[min]] and [[max]].
 *
 * Additional to validating the date it can also export the parsed timestamp as a machine readable format
 * which can be configured using [[timestampAttribute]]. For values that include time information (not date-only values)
 * also the time zone will be adjusted. The time zone of the input value is assumed to be the one specified by the [[timeZone]]
 * property and the target timeZone will be UTC when [[timestampAttributeFormat]] is `null` (exporting as UNIX timestamp)
 * or [[timestampAttributeTimeZone]] otherwise. If you want to avoid the time zone conversion, make sure that [[timeZone]] and
 * [[timestampAttributeTimeZone]] are the same.

    /**
     * @var string|null the date format that the value being validated should follow.
     * This can be a date time pattern as described in the [ICU manual](https://unicode-org.github.io/icu/userguide/format_parse/datetime/#datetime-format-syntax).
     *
     * Alternatively this can be a string prefixed with `php:` representing a format that can be recognized by the PHP Datetime class.
     * Please refer to <https://www.php.net/manual/en/datetime.createfromformat.php> on supported formats.
     *
     * If this property is not set, the default value will be obtained from `Yii::$app->formatter->dateFormat`, see [[\yii\i18n\Formatter::dateFormat]] for details.
     * Since version 2.0.8 the default value will be determined from different formats of the formatter class,
     * dependent on the value of [[type]]:
     *
     * - if type is [[TYPE_DATE]], the default value will be taken from [[\yii\i18n\Formatter::dateFormat]],
     * - if type is [[TYPE_DATETIME]], it will be taken from [[\yii\i18n\Formatter::datetimeFormat]],
     * - and if type is [[TYPE_TIME]], it will be [[\yii\i18n\Formatter::timeFormat]].
     *
     * Here are some example values:
     *
     * ```php
     * 'MM/dd/yyyy' // date in ICU format
     * 'php:m/d/Y' // the same date in PHP format
     * 'MM/dd/yyyy HH:mm' // not only dates but also times can be validated
     * ```
     *
     * **Note:** the underlying date parsers being used vary dependent on the format. If you use the ICU format and
     * the [PHP intl extension](https://www.php.net/manual/en/book.intl.php) is installed, the [IntlDateFormatter](https://www.php.net/manual/en/intldateformatter.parse.php)
     * is used to parse the input value. In all other cases the PHP [DateTime](https://www.php.net/manual/en/datetime.createfromformat.php) class
     * is used. The IntlDateFormatter has the advantage that it can parse international dates like `12. Mai 2015` or `12 мая 2014`, while the
     * PHP parser is limited to English only. The PHP parser however is more strict about the input format as it will not accept
     * `12.05.05` for the format `php:d.m.Y`, but the IntlDateFormatter will accept it for the format `dd.MM.yyyy`.
     * If you need to use the IntlDateFormatter you can avoid this problem by specifying a [[min|minimum date]].

24		* It is further possible to limit the date within a certain range using [[min]] and [[max]].
25		*
26		* Additional to validating the date it can also export the parsed timestamp as a machine readable format

30		* or [[timestampAttributeTimeZone]] otherwise. If you want to avoid the time zone conversion, make sure that [[timeZone]] and

77		*
78		* Alternatively this can be a string prefixed with `php:` representing a format that can be recognized by the PHP Datetime class.
79		* Please refer to <https://www.php.net/manual/en/datetime.createfromformat.php> on supported formats.
80		*
81		* If this property is not set, the default value will be obtained from `Yii::$app->formatter->dateFormat`, see [[\yii\i18n\Formatter::dateFormat]] for details.
82		* Since version 2.0.8 the default value will be determined from different formats of the formatter class,
83		* dependent on the value of [[type]]:
84		*
85		* - if type is [[TYPE_DATE]], the default value will be taken from [[\yii\i18n\Formatter::dateFormat]],
86		* - if type is [[TYPE_DATETIME]], it will be taken from [[\yii\i18n\Formatter::datetimeFormat]],
87		* - and if type is [[TYPE_TIME]], it will be [[\yii\i18n\Formatter::timeFormat]].
88		*
89		* Here are some example values:
90		*
91		* ```php
92		* 'MM/dd/yyyy' // date in ICU format
93		* 'php:m/d/Y' // the same date in PHP format
94		* 'MM/dd/yyyy HH:mm' // not only dates but also times can be validated
95		* ```
96		*
97		* Note: the underlying date parsers being used vary dependent on the format. If you use the ICU format and
98		* the [PHP intl extension](https://www.php.net/manual/en/book.intl.php) is installed, the [IntlDateFormatter](https://www.php.net/manual/en/intldateformatter.parse.php)
99		* is used to parse the input value. In all other cases the PHP [DateTime](https://www.php.net/manual/en/datetime.createfromformat.php) class
100		* is used. The IntlDateFormatter has the advantage that it can parse international dates like `12. Mai 2015` or `12 мая 2014`, while the
101		* PHP parser is limited to English only. The PHP parser however is more strict about the input format as it will not accept
102		* `12.05.05` for the format `php:d.m.Y`, but the IntlDateFormatter will accept it for the format `dd.MM.yyyy`.
103		* If you need to use the IntlDateFormatter you can avoid this problem by specifying a [[min\|minimum date]].
