* Formats a date value according to locale rules.
*
* The following tabled describes the formatting options.
* Only the `en-US` locale data comes with Angular. To localize dates
* in another language, you must import the corresponding locale data.
* See the [I18n guide](guide/i18n#i18n-pipes) for more information.

*
* The result of this pipe is not reevaluated when the input is mutated. To avoid the need to
* reformat the date on every change-detection cycle, treat the date as an immutable object
* and change the reference when the pipe needs to run again.
*
* ### Pre-defined format options
*
* Examples are given in `en-US` locale.
*
* - `'short'`: equivalent to `'M/d/yy, h:mm a'` (`6/15/15, 9:03 AM`).
* - `'medium'`: equivalent to `'MMM d, y, h:mm:ss a'` (`Jun 15, 2015, 9:03:01 AM`).
* - `'long'`: equivalent to `'MMMM d, y, h:mm:ss a z'` (`June 15, 2015 at 9:03:01 AM
* GMT+1`).
* - `'full'`: equivalent to `'EEEE, MMMM d, y, h:mm:ss a zzzz'` (`Monday, June 15, 2015 at
* 9:03:01 AM GMT+01:00`).
* - `'shortDate'`: equivalent to `'M/d/yy'` (`6/15/15`).
* - `'mediumDate'`: equivalent to `'MMM d, y'` (`Jun 15, 2015`).
* - `'longDate'`: equivalent to `'MMMM d, y'` (`June 15, 2015`).
* - `'fullDate'`: equivalent to `'EEEE, MMMM d, y'` (`Monday, June 15, 2015`).
* - `'shortTime'`: equivalent to `'h:mm a'` (`9:03 AM`).
* - `'mediumTime'`: equivalent to `'h:mm:ss a'` (`9:03:01 AM`).
* - `'longTime'`: equivalent to `'h:mm:ss a z'` (`9:03:01 AM GMT+1`).
* - `'fullTime'`: equivalent to `'h:mm:ss a zzzz'` (`9:03:01 AM GMT+01:00`).
*
* ### Custom format options
*
* You can construct a format string using symbols to specify the components
* of a date-time value, as described in the following table.
* Format details depend on the locale.
* Fields marked with (*) are only available if you have imported a locale-specific data set.
*
* | Field type | Format | Description | Example Value |

* Note that time zone correction is not applied to an ISO string that has no time component, such as "2016-09-19"
*
* When the expression is a ISO string without time (e.g. 2016-09-19) the time zone offset is not
* applied and the formatted text will have the same day, month and year of the expression.
* ### Format examples
*
* WARNINGS:
* - this pipe has only access to en-US locale data by default. If you want to localize the dates
* in another language, you will have to import data for other locales.
* See the ["I18n guide"](guide/i18n#i18n-pipes) to know how to import additional locale
* data.
* - Fields suffixed with * are only available in the extra dataset.
* See the ["I18n guide"](guide/i18n#i18n-pipes) to know how to import extra locale
* data.
* - this pipe is marked as pure hence it will not be re-evaluated when the input is mutated.
* Instead users should treat the date as an immutable object and change the reference when the
* pipe needs to re-run (this is to avoid reformatting the date on every change detection run
* which would be an expensive operation).
* These examples transform a date into various formats,
* assuming that `dateObj` is a JavaScript `Date` object for
* year: 2015, month: 6, day: 15, hour: 21, minute: 43, second: 11.
* The output is in the local time for the 'en-US' locale.
*
* ### Examples
* ```
* {{ dateObj | date }} // output is 'Jun 15, 2015'
* {{ dateObj | date:'medium' }} // output is 'Jun 15, 2015, 9:43:11 PM'
* {{ dateObj | date:'shortTime' }} // output is '9:43 PM'

* The following component uses a date pipe to display the current date in two different formats.

* ```
* @Component({

* <p>Today is {{today | date}}</p>
* <p>Or if you prefer, {{today | date:'fullDate'}}</p>
* <p>The time is {{today | date:'jmZ'}}</p>
* </div>`
* })
* // Get the current date and time as a date-time value.
* export class DatePipeComponent {
* today: number = Date.now();
* }

* @param value The date expression: a `Date` object, a number
* (milliseconds since UTC epoch), or an ISO string (https://www.w3.org/TR/NOTE-datetime).
* @param format The date/time components to include, using predefined options or a
