How to get standard format date in android

Question

if i try the below code for eg:

i will set the date as Fri July 25 2014 10:00 AM. which gives date in milliseconds as 1402080056000,

now if i try to read the same milliseconds to date as below

  long time = 1402080056000;

  Date mydate = new Date(time);

mydate variable shows date as Sat Jun 25 00:10:56 IST 2014

  String DateTimeString = DateFormat.getDateTimeInstance().format(new Date(time));

with the above statement in DateTimeString i get date as Jun 25 , 2014 12:10:56 AM

How to read the datetime present in 1402080056000 to Fri July 25 2014 10:00 AM

Just need to work on the format string,

String dateTimeString= 
String.valueOf(new SimpleDateFormat("dd-MM-yyyy hh:mm").format(new Date(time)));

Explicitly set time zone:

SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-yyyy hh:mm");
dateFormat.setTimeZone(TimeZone.getTimeZone("GMT"));
String result = String.valueOf(dateFormat.format(millis));

Also, this would be useful Regarding Timezones and Java

try below code:

private String convertMilliToDate(long timestamp) {

        DateFormat formatter = new SimpleDateFormat("YOUR DATE FORMAT");

        // Create a calendar object that will convert the date and time value in
        // milliseconds to date.
        Calendar calendar = Calendar.getInstance();
        calendar.setTimeInMillis(time);
        return formatter.format(calendar.getTime());
    }

Hi, thanks, if i pass timestamp as 0, i get datetime as 01:01:70:05:30:00. But why i'm getting 5.30 AM, it should be 00 right? – Naruto Apr 18 '14 at 12:56

if you will give wrong data to convert then by default it will convert to this date like 1-1-1970. Because timestamp calculations starts from that date. So you must need to give valid timestamp to convert. – Pratik Dasa Apr 21 '14 at 04:48

Try this:

String date= DateFormat.format("dd/MM/yyyy hh:mm:ss", new Date(date_in_milis)).toString();

Date-time work is easier using the Joda-Time library, which works on Android.

long millis = 1402080056000L;

DateTimeZone timeZoneIndia = DateTimeZone.forID( "Asia/Kolkata" );
DateTime dateTimeIndia = new DateTime( millis, timeZoneIndia );

DateTime dateTimeFrance = dateTimeIndia.withZone( DateTimeZone.forID( "Europe/Paris" ) );

DateTime dateTimeUtc = dateTimeIndia.withZone( DateTimeZone.UTC );

To parse a string as a date-time, search StackOverflow for "Joda parse" to find many examples.
