Answer 1

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.

Answer 2

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?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

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.

Answer 3

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