tl;dr

You are asking for the ISO 8601 format set to UTC time zone.

Instant.now().toString()

2018-01-25T22:50:24.702645Z

java.time

The java.time classes use the standard ISO 8601 formats by default when parsing or generating strings.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Get the current moment in UTC:

Instant instant = Instant.now() ;

To generate a string in standard ISO 8601 format:

String output = instant.toString() ;  // Generate string in standard format.

Going the other direction, parsing such a string.

Instant instant = Instant.parse( "2013-11-26T03:16:00.000Z" );

Search Stack Overflow for much discussion of java.time classes such as ZoneId, ZonedDateTime, and OffsetDateTime.

Joda-Time

Update: The Joda-Time project is now in maintenance mode, with the team advising migration to the java.time classes.

ISO 8601 formats are the default for the Joda-Time 2.3 library.

System.out.println( "Now: " + new org.joda.time.DateTime( org.joda.time.DateTimeZone.UTC ) );

When run…

Now: 2013-11-26T20:25:12.014Z

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

There is documentation readily available for Android's SimpleDateFormat class at:

http://developer.android.com/reference/java/text/SimpleDateFormat.html

Also appears to have been answered before. Among other places.

  • FYI, the troublesome old date-time classes such as `java.util.Date`, `java.util.Calendar`, and `java.text.SimpleDateFormat` are now legacy, supplanted by the [java.time](https://docs.oracle.com/javase/9/docs/api/java/time/package-summary.html) classes. Much of the java.time functionality is back-ported to Java 6 & Java 7 in the [***ThreeTen-Backport***](http://www.threeten.org/threetenbp/) project. Further adapted for earlier Android in the [***ThreeTenABP***](https://github.com/JakeWharton/ThreeTenABP) project. See [*How to use ThreeTenABP…*](http://stackoverflow.com/q/38922754/642706). – Basil Bourque Jan 26 '18 at 00:56

Use SimpleDateFormat sd= new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
