/**
 * The `NbTimePickerDirective` is form control that gives you ability to select a time. The timepicker
 * is shown when input receives a `focus` event.
 * ```html
 * <input [nbTimepicker]="timepicker">
 * <nb-timepicker #timepicker></nb-timepicker>
 * ```
 *
 * @stacked-example(Showcase, timepicker/timepicker-showcase.component)
 *
 * ### Installation
 *
 * Import `NbTimepickerModule.forRoot()` to your root module.
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbTimepickerModule.forRoot(),
 *   ],
 * })
 * export class AppModule { }
 * ```
 * And `NbTimepickerModule` to your feature module.
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbTimepickerModule,
 *   ],
 * })
 * export class PageModule { }
 *
 * ```

 * <div class="note-body">
 * Timepicker uses native Date object by default, which doesn't support parsing by custom format.
 * According to the ECMAScript specification, the only supported format is a format described by ISO 8061 standard.
 * This standard requires date part to be included in the date string,
 * meaning you have to type a date+time in the input.
 * We highly recommend you to use NbDateFnsDateModule or NbMomentDateModule to be able to support time only strings in
 * the timepicker inputs. These modules use date-fns and moment date libraries, which provide capabilities
 * to parse time only strings.
 * See "Formatting Issue" at
 * <a href="https://akveo.github.io/nebular/docs/components/datepicker/overview#formatting-issue">Date picker docs</a>
 * for installation instructions.

 * ### Usage
 *
 * To show seconds column along with hours and minutes use `withSeconds` input
 *
 * ```html
 * <input [nbTimepicker]="timepicker">
 * <nb-timepicker #timepicker withSeconds></nb-timepicker>
 * ```
 * @stacked-example(Time picker with seconds, timepicker/timepicker-with-seconds.component)
 *
 * To force timepicker work in 12 hours format, use `twelveHoursFormat` input.
 * By default, timepicker choose 12 or 24 formats based on application locale standards
 *
 * ```html
 * <input [nbTimepicker]="timepicker" twelveHoursFormat>
 * <nb-timepicker #timepicker></nb-timepicker>
 * ```
 *
 * @stacked-example(Twelve hours format showcase, timepicker/timepicker-twelve-hours-format.component)
 *
 * A single column picker with options value as time and minute, so users won’t be able to pick
 * hours and minutes individually.
 * You can control options minutes offset via `step` input, e.g.: 11:00, 11:20, 11:40...'
 *
 * @stacked-example(Single column, timepicker/timepicker-single-column.component)
 *
 * Timepicker support forms and reactive forms API so you can provide value using `formControl` and `ngModel` directives
 * @stacked-example(Form control, timepicker/timepicker-form-control.component)
 *
 * <input [nbTimepicker]="timepicker" twelveHoursFormat>
 * <nb-timepicker #timepicke [formControl]="formControl"></nb-timepicker>
 *
 * @stacked-example(NgModel, timepicker/timepicker-ng-model.component)
 *
 * <input [nbTimepicker]="timepicker" twelveHoursFormat>
 * <nb-timepicker #timepicke [ngModel]="date"></nb-timepicker>
 *
 * You can provide localized versions of the timepicker text via the `localization` property of the config
 * object passed to the `forRoot` or `forChild` methods of the `NbTimepickerModule`:
 * ```ts
 * @NgModule({
 *   imports: [
 *     // ...
 *     NbTimepickerModule.forRoot({
 *       localization: {
 *         hoursText: 'Hr',
 *         minutesText: 'Min',
 *         secondsText: 'Sec',
 *         ampmText: 'Am/Pm',
 *       }
 *     }),
 *   ],
 * })
 * export class AppModule { }
 * ```
