/**
* @name DateTime
* @description
* The Date/Time Picker displays a dialog from the bottom of a page.
*
*
* It is similar to the native `<input type="datetime-local">` element.
* However, Ionic's Date/Time component makes it easy for developers to display
* the date in their preferred format and manage the date from their JavaScript.
* Additionally, the Date/Time component makes it easier for users to scroll through
* and individually select parts of date and time values from an easy to user interface.
*
* ```html
* <ion-item>
* <ion-label>Date</ion-label>
* <ion-datetime displayFormat="MM/DD/YYYY" [(ngModel)]="myDate">
* </ion-datetime>
* </ion-item>
* ```
*
*
* ### Display and Picker Formats
*
* Datetime values can be displayed in many different formats, so it is best to
* let the app decide exactly how to display it. To do so, `ion-datetime` uses
* a common format seen in many other libraries and programming languages:
*
* | Format | Description | Example |
* |---------|--------------------------------|-------------------------|
* | `YYYY` | Year, 4 digits | `2018` |
* | `YY` | Year, 2 digits | `18` |
* | `M` | Month | `1` ... `12` |
* | `MM` | Month, leading zero | `01` ... `12` |
* | `MMM` | Month, short name | `Jan` |
* | `MMMM` | Month, full name | `January` |
* | `D` | Day | `1` ... `31` |
* | `DD` | Day, leading zero | `01` ... `31` |
* | `DDD` | Day, short name | `Fri` |
* | `DDDD` | Day, full name | `Friday` |
* | `H` | Hour, 24-hour | `0` ... `23` |
* | `HH` | Hour, 24-hour, leading zero | `00` ... `23` |
* | `h` | Hour, 12-hour | `1` ... `12` |
* | `hh` | Hour, 12-hour, leading zero | `01` ... `12` |
* | `a` | 12-hour time period, lowercase | `am` `pm` |
* | `A` | 12-hour time period, uppercase | `AM` `PM` |
* | `m` | Minute | `1` ... `59` |
* | `mm` | Minute, leading zero | `01` ... `59` |
* | `s` | Second | `1` ... `59` |
* | `ss` | Second, leading zero | `01` ... `59` |
* | `Z` | UTC Timezone Offset | `Z or +HH:mm or -HH:mm` |
*
* **Important**: See the [Month Names and Day of the Week Names](#month-names-and-day-of-the-week-names)
* section below on how to use different names for the month and day.
*
* The `displayFormat` input allows developers to specify how a date's value
* should be displayed within the `ion-datetime`. The `pickerFormat` decides
* which datetime picker columns should be shown, the order of the columns, and
* which format to display the value in. If a `pickerFormat` is not provided
* then it'll use the `displayFormat` instead. In most cases only providing the
* `displayFormat` is needed.
*
* In the example below, the datetime's display would use the month's short
* name, the 1 digit day in the month, and a 4 digit year.
*
* ```html
* <ion-item>
* <ion-label>Date</ion-label>
* <ion-datetime displayFormat="MMM DD, YYYY" [(ngModel)]="myDate">
* </ion-datetime>
* </ion-item>
* ```
*
* In this example, the datetime's display would only show hours and minutes,
* and the hours would be in the 24-hour format. Note that the divider between
* the hours and minutes, in this case the `:` character, can be have any
* character which the app chooses to use as the divider.
*
* ```html
* <ion-item>
* <ion-label>Date</ion-label>
* <ion-datetime displayFormat="HH:mm" [(ngModel)]="myDate">
* </ion-datetime>
* </ion-item>
* ```
*
*
* ### Datetime Data
*
* Historically, handling datetime data within JavaScript, or even within HTML
* inputs, has always been a challenge. Specifically, JavaScript's `Date` object is
* notoriously difficult to correctly parse apart datetime strings or to format
* datetime values. Even worse is how different browsers and JavaScript versions
* parse various datetime strings differently, especially per locale. Additional,
* developers face even more challenges when dealing with timezones using
* JavaScript's core `Date` object.
*
* But no worries, all is not lost! Ionic's datetime input has been designed so
* developers can avoid the common pitfalls, allowing developers to easily format
* datetime data within the input, and give the user a simple datetime picker for a
* great user experience. Oddly enough, one of the best ways to work with datetime
* values in JavaScript is to not use the `Date` object at all.
*
* ##### ISO 8601 Datetime Format: YYYY-MM-DDTHH:mmZ
*
* For all the reasons above, and how datetime data is commonly saved within databases,
* Ionic uses the [ISO 8601 datetime format](https://www.w3.org/TR/NOTE-datetime)
* for both its input value, and output value. The value is simply a string, rather
* than using JavaScript's `Date` object, and it strictly follows the standardized
* ISO 8601 format. Additionally, when using the ISO datetime string format, it makes
* it easier on developers when passing data within JSON objects, and sending databases
* a standardized datetime format which it can be easily parse apart and formatted.
* Because of the strict adherence to the ISO 8601 format, and not involving the hundreds
* of other format possibilities and locales, this approach actually makes it easier
* for Ionic apps and backend-services to manage datetime data.
*
* An ISO format can be used as a simple year, or just the hour and minute, or get more
* detailed down to the millisecond and timezone. Any of the ISO formats below can be used,
* and after a user selects a new date, Ionic will continue to use the same ISO format
* which datetime value was originally given as.
*
* | Description | Format | Datetime Value Example |
* |----------------------|------------------------|------------------------------|
* | Year | YYYY | 1994 |
* | Year and Month | YYYY-MM | 1994-12 |
* | Complete Date | YYYY-MM-DD | 1994-12-15 |
* | Date and Time | YYYY-MM-DDTHH:mm | 1994-12-15T13:47 |
* | UTC Timezone | YYYY-MM-DDTHH:mm:ssTZD | 1994-12-15T13:47:20.789Z |
* | Timezone Offset | YYYY-MM-DDTHH:mm:ssTZD | 1994-12-15T13:47:20.789+5:00 |
* | Hour and Minute | HH:mm | 13:47 |
* | Hour, Minute, Second | HH:mm:ss | 13:47:20 |
*
* Note that the year is always four-digits, milliseconds (if it's added) is always
* three-digits, and all others are always two-digits. So the number representing
* January always has a leading zero, such as `01`. Additionally, the hour is always
* in the 24-hour format, so `00` is `12am` on a 12-hour clock, `13` means `1pm`,
* and `23` means `11pm`.
*
* It's also important to note that neither the `displayFormat` or `pickerFormat` can
* set the datetime value's output, which is the value that sent the the component's
* `ngModel`. The format's are merely for displaying the value as text and the picker's
* interface, but the datetime's value is always persisted as a valid ISO 8601 datetime
* string.
*
*
* ### Min and Max Datetimes
*
* Dates are infinite in either direction, so for a user selection there should be at
* least some form of restricting the dates can be selected. Be default, the maximum
* date is to the end of the current year, and the minimum date is from the beginning
* of the year that was 100 years ago.
*
* To customize the minimum and maximum datetime values, the `min` and `max` component
* inputs can be provided which may make more sense for the app's use-case, rather
* than the default of the last 100 years. Following the same IS0 8601 format listed
* in the table above, each component can restrict which dates can be selected by the
* user. Below is an example of restricting the date selection between the beginning
* of 2016, and October 31st of 2020:
*
* ```html
* <ion-item>
* <ion-label>Date</ion-label>
* <ion-datetime displayFormat="MMMM YYYY" min="2016" max="2020-10-31" [(ngModel)]="myDate">
* </ion-datetime>
* </ion-item>
* ```
*
*
* ### Month Names and Day of the Week Names
*
* At this time, there is no one-size-fits-all standard to automatically choose the correct
* language/spelling for a month name, or day of the week name, depending on the language
* or locale. Good news is that there is an
* [Intl.DateTimeFormat](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/DateTimeFormat)
* standard which *most* browsers have adopted. However, at this time the standard has not
* been fully implemented by all popular browsers so Ionic is unavailable to take advantage
* of it *yet*. Additionally, Angular also provides an internationalization service, but it
* is still under heavy development so Ionic does not depend on it at this time.
*
* All things considered, the by far easiest solution is to just provide an array of names
* if the app needs to use names other than the default English version of month and day
* names. The month names and day names can be either configurated at the app level, or
* individual `ion-datetime` level.
*
* ##### App Config Level
*
* ```ts
* @App({
* config: {
* monthNames: ['janeiro, 'fevereiro', 'mar\u00e7o', ... ],
* monthShortNames: ['jan', 'fev', 'mar', ... ],
* dayNames: ['domingo', 'segunda-feira', 'ter\u00e7a-feira', ... ],
* dayShortNames: ['dom', 'seg', 'ter', ... ],
* }
* })
* ```
*
* ##### Component Input Level
*
* ```html
* <ion-item>
* <ion-label>Período</ion-label>
* <ion-datetime displayFormat="DDDD MMM D, YYYY" [(ngModel)]="myDate"
* [monthNames]="['janeiro, 'fevereiro', 'mar\u00e7o', ... ]"
* [monthShortNames]="['jan', 'fev', 'mar', ... ]"
* [dayNames]="['domingo', 'segunda-feira', 'ter\u00e7a-feira', ... ]"
* [dayShortNames]="['dom', 'seg', 'ter', ... ]"
* ></ion-datetime>
* </ion-item>
* ```
*
*
* ### Advanced Datetime Validation and Manipulation
*
* The datetime picker provides the simplicity of selecting an exact format, and persists
* the datetime values as a string using the standardized
* [ISO 8601 datetime format](https://www.w3.org/TR/NOTE-datetime).
* However, it's important to note that `ion-datetime` does not attempt to solve all
* situtations when validating and manipulating datetime values. If datetime values need
* to be parsed from a certain format, or manipulated (such as adding 5 days to a date,
* subtracting 30 minutes), or even formatting data to a specific locale, then we highly
* recommend using [moment.js](http://momentjs.com/) to "Parse, validate, manipulate, and
* display dates in JavaScript". [Moment.js](http://momentjs.com/) has quickly become
* our goto standard when dealing with datetimes within JavaScript, but Ionic does not
* prepackage this dependency since most apps will not require it, and its locale
* configuration should be decided by the end-developer.
