Converting current time to this format: “2017-04-25T17:12:42+01:00”

问题

How can I convert current time to this format:

 "2017-04-25T17:12:42+01:00"

The closest I could get is this:

"2017-05-16T19:58:21+0100"

by using this format:

SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZZZ").format(new Date())

Thanks

You should use the modern Java 8 java.time package, more specifically DateTimeFormatter, the ISO_OFFSET_DATE_TIME.

From the docs:

public static final DateTimeFormatter ISO_OFFSET_DATE_TIME

The ISO date-time formatter that formats or parses a date-time with an offset, such as '2011-12-03T10:15:30+01:00'.

Working code:

import java.time.ZonedDateTime;
import java.time.format.DateTimeFormatter;

public class Main
{
  public static void main(String[] args)
  {
    ZonedDateTime date = ZonedDateTime.now();
    String text = date.format(DateTimeFormatter.ISO_OFFSET_DATE_TIME);
    System.out.println(text);
  }
}

Result:

> run Main
2017-05-19T13:03:16.167+02:00

ZZZ is RFC 822 time zone like this: -0800;

XXX is ISO 8601 time zone like this: -08:00;

Use XXX if want to second foramt and don't want use ISO_OFFSET_DATE_TIME, for example, want to display “01/15/2000T14:44:59-08:00”:

DateTimeFormatter.ofPattern("MM/dd/yyyy'T'HH:mm:ssXXX").format(...);

回答3:

You can use "yyyy-MM-dd'T'HH:mm:ssXXX" as pattern instead of yyyy-MM-dd'T'HH:mm:ssZZZ, see the examples here

SimpleDateFormat will do a thing for you

SimpleDateFormat formatter= new SimpleDateFormat("yyyy-MM-dd");

formatter.format(date);
