convert timestamp into current date in android

Question

I have a problem in displaying the date,I am getting timestamp as 1379487711 but as per this the actual time is 9/18/2013 12:31:51 PM but it displays the time as 17-41-1970. How to show it as current time.

for displaying time I have used the following method:

private String getDate(long milliSeconds) {
    // Create a DateFormatter object for displaying date in specified
    // format.
    SimpleDateFormat formatter = new SimpleDateFormat("dd-mm-yyyy");
    // Create a calendar object that will convert the date and time value in
    // milliseconds to date.
    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis((int) milliSeconds);
    return formatter.format(calendar.getTime());
}

Are you sure this is in mili-seconds and not simple seconds? use this to check your time: http://www.onlineconversion.com/unix_time.htm — Sean, Sep 21 '13 at 07:10
I am using timestamp as long time = System.currentMilliSeconds; — jkk, Sep 21 '13 at 07:22
You can try this if you want, for me it works perfectly. [Firebase Functions](https://stackoverflow.com/questions/38593245/how-to-get-current-timestamp-of-firebase-server-in-milliseconds/59448648#59448648) — AllanRibas, Jun 07 '20 at 16:32

private String getDate(long time) {
    Calendar cal = Calendar.getInstance(Locale.ENGLISH);
    cal.setTimeInMillis(time * 1000);
    String date = DateFormat.format("dd-MM-yyyy", cal).toString();
    return date;
}

notice that I put the time in setTimeInMillis as long and not as int, notice my date format has MM and not mm (mm is for minutes, and not months, this is why you have a value of "41" where the months should be)

for Kotlin users:

fun getDate(timestamp: Long) :String {
   val calendar = Calendar.getInstance(Locale.ENGLISH)
   calendar.timeInMillis = timestamp * 1000L
   val date = DateFormat.format("dd-MM-yyyy",calendar).toString()
   return date
}

For converting time stamp to current time

Calendar calendar = Calendar.getInstance();
TimeZone tz = TimeZone.getDefault();
calendar.add(Calendar.MILLISECOND, tz.getOffset(calendar.getTimeInMillis()));
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss", Locale.getDefault());
java.util.Date currenTimeZone=new java.util.Date((long)1379487711*1000);
Toast.makeText(TimeStampChkActivity.this, sdf.format(currenTimeZone), Toast.LENGTH_SHORT).show();

convert timestamp into current date:

private Date getDate(long time) {    
    Calendar cal = Calendar.getInstance();
       TimeZone tz = cal.getTimeZone();//get your local time zone.
       SimpleDateFormat sdf = new SimpleDateFormat("dd/MM/yyyy hh:mm a");
       sdf.setTimeZone(tz);//set time zone.
       String localTime = sdf.format(new Date(time) * 1000));
       Date date = new Date();
       try {
            date = sdf.parse(localTime);//get local date
        } catch (ParseException e) {
            e.printStackTrace();
        }
      return date;

  DateFormat df = new SimpleDateFormat("HH:mm", Locale.US);
  final String time_chat_s = df.format(time_stamp_value);

The time_stamp_value variable type is long

With your code it will look something like so:

private String getDate(long time_stamp_server) {

    SimpleDateFormat formatter = new SimpleDateFormat("dd-mm-yyyy");
    return formatter.format(time_stamp_server);
}

I change "milliseconds" to time_stamp_server. Consider changing the name of millisecond to "c" or to something more global. "c" is really good because it relates to time and to computing in much more global way than milliseconds does. So, you do not necessarily need a calendar object to convert and it should be as simple as that.

tl;dr

You have a number of whole seconds since 1970-01-01T00:00:00Z rather than milliseconds.

Instant
.ofEpochSecond( 1_379_487_711L )
.atZone( 
    ZoneId.of( "Africa/Tunis" ) 
)
.toLocalDate()
.format(
    DateTimeFormatter.ofPattern( "dd-MM-uuuu" ) 
)

See this code run at Ideone.com.

Whole seconds versus Milliseconds

As stated above, you confused a count-of-seconds with a count-of-milliseconds.

Your confusion demonstrates why using a mere integer to represent a moment is a poor choice. Instead, use text, always in standard ISO 8601 format.

Using java.time

The other Answers may be correct but are outdated. The troublesome old date-time classes used there are now legacy, supplanted by the java.time classes. For Android, see the last bullets below.

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).

Instant instant = Instant.ofEpochSecond( 1_379_487_711L ) ;

instant.toString(): 2013-09-18T07:01:51Z

Apply the time zone through which you want to view this moment.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z ) ;

zdt.toString(): 2013-09-18T03:01:51-04:00[America/Montreal]

Generate a string representing this value in your desired format.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd-MM-uuuu" ) ;
String output = zdt.format( f ) ;

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, Java 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 Java 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.

If your result always returns 1970, try this way :

Calendar cal = Calendar.getInstance(Locale.ENGLISH);
cal.setTimeInMillis(timestamp * 1000L);
String date = DateFormat.format("dd-MM-yyyy hh:mm:ss", cal).toString();

You need to multiple your TS value by 1000

It’s so easy to use it.

I got this from here: http://www.java2s.com/Code/Android/Date-Type/CreateDatefromtimestamp.htm

None of the above answers worked for me.

Calendar c = Calendar.getInstance();
c.setTimeInMillis(Integer.parseInt(tripBookedTime) * 1000L);
Date d = c.getTime();
SimpleDateFormat sdf = new SimpleDateFormat("MMM dd, yyyy");
return sdf.format(d);

And by the way: ("dd-MM-yyyy", cal) is not recognized by Android - "Cannot resolve method".

These terrible date-time classes were supplanted years ago by the modern *java.time* classes. Suggesting their use in 2019 is poor advice. – Basil Bourque Jun 26 '19 at 00:29
Well, it works without single trouble or any warnings or notations from the latest AndroidStudio 3.4.1 – ekashking Jun 26 '19 at 00:33

(A) You should not be asking for a date-time from the database as a a mere integer number (a count from epoch). You should be retrieving a date-time object, a `java.time.OffsetDateTime` object. (B) If you do retrieve an integer count-from-epoch of first moment of 1970 in UTC, what about the `Instant.ofEpochSecond( 1_379_487_711L ).atZone( ZoneId.of( "Africa/Tunis" ) ).format( DateTimeFormatter.ofPattern( "dd-MM-uuuu" ) )` given in [my Answer](https://stackoverflow.com/a/46416290/642706) did not work for you?

If you want show chat message look like what up app, then use below method. date format you want change according to your requirement.

public String DateFunction(long timestamp, boolean isToday)
{
    String sDate="";
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
    Calendar c = Calendar.getInstance();
    Date netDate = null;
    try {
        netDate = (new Date(timestamp));
        sdf.format(netDate);
        sDate = sdf.format(netDate);
        String currentDateTimeString = sdf.format(c.getTime());
        c.add(Calendar.DATE, -1);
        String yesterdayDateTimeString =  sdf.format(c.getTime());
        if(currentDateTimeString.equals(sDate) && isToday) {

current date and time:

 private String getDateTime() {
        Calendar calendar = Calendar.getInstance(Locale.ENGLISH);
        Long time = System.currentTimeMillis();
        calendar.setTimeInMillis(time);

       //dd=day, MM=month, yyyy=year, hh=hour, mm=minute, ss=second.

        String date = DateFormat.format("dd-MM-yyyy hh:mm:ss",calendar).toString();
        return date;
    }

Note: If your result always returns 1970, try this way :

Calendar calendar = Calendar.getInstance(Locale.ENGLISH);
calender.setTimeInMillis(time * 1000L);
String date = DateFormat.format("dd-MM-yyyy hh:mm:ss", calendar).toString();

Try this, it works perfect

    long time = us.getTimeStamp();
    SimpleDateFormat dateFormat = new SimpleDateFormat("dd-MM-YYYY - hh:mm a");
    Log.d("rajbhai", String.valueOf(us.getTimeStamp()));
    holder.binding.chaterName.setText(dateFormat.format(new Date(time)));

Consider throwing away the long outmoded and notoriously troublesome `SimpleDateFormat` and friends. Use [desugaring](https://developer.android.com/studio/write/java8-support-table) in order to use [java.time, the modern Java date and time API](https://docs.oracle.com/javase/tutorial/datetime/). It is so much nicer to work with. Also your format pattern string is incorrect (this time I mean it, have double-checked). – Ole V.V. Sep 19 '22 at 16:27
