+WARNINGS:
+-
+
- 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). + +
- this pipe uses the Internationalization API. Therefore it is only reliable in Chrome and + Opera + browsers. + +
Examples
+Assuming dateObj is (year: 2015, month: 6, day: 15, hour: 21, minute: 43,
+ second: 11)
+ in the local time and locale is 'en-US':
+ @Component({
+ selector: 'date-pipe',
+ template: `<div>
+ <p>Today is {{today | date}}</p>
+ <p>Or if you prefer, {{today | date:'fullDate'}}</p>
+ <p>The time is {{today | date:'jmZ'}}</p>
+ </div>`
+ })
+ export class DatePipeComponent {
+ today: number = Date.now();
+ }
