How to Convert Milliseconds to Date Format in Android

how to convert milliseconds to date format in android?

Just Try this Sample code:-

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;

public class Test {

/**
 * Main Method
 */
public static void main(String[] args) {
    System.out.println(getDate(82233213123L, "dd/MM/yyyy hh:mm:ss.SSS"));
}

/**
 * Return date in specified format.
 * @param milliSeconds Date in milliseconds
 * @param dateFormat Date format 
 * @return String representing date in specified format
 */
public static String getDate(long milliSeconds, String dateFormat)
{
    // Create a DateFormatter object for displaying date in specified format.
    SimpleDateFormat formatter = new SimpleDateFormat(dateFormat);

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

Converting milliseconds to Date object

try my code if you a

long currentTime = System.currentTimeMillis();
TimeZone tz = TimeZone.getDefault();
Calendar cal = GregorianCalendar.getInstance(tz);
int offsetInMillis = tz.getOffset(cal.getTimeInMillis());

currentTime -= offsetInMillis;
Date date = new Date(currentTime);

it is work for me

Android : Convert millisecond to time

You could use SimpleDateFormat, but be aware that you should set both the time zone and the locale appropriately:

DateFormat formatter = new SimpleDateFormat("HH:mm:ss", Locale.US);
formatter.setTimeZone(TimeZone.getTimeZone("UTC"));
String text = formatter.format(new Date(millis));

The time zone part is important, as otherwise it will use the system-default time zone, which would usually be inappropriate. Note that the Date here will be on January 1st 1970, UTC - assuming your millisecond value is less than 24 hours.

how to get date from milliseconds in android

you can use like this

Calendar cl = Calendar.getInstance();
cl.setTimeInMillis(milliseconds);  //here your time in miliseconds
String date = "" + cl.get(Calendar.DAY_OF_MONTH) + ":" + cl.get(Calendar.MONTH) + ":" + cl.get(Calendar.YEAR);
String time = "" + cl.get(Calendar.HOUR_OF_DAY) + ":" + cl.get(Calendar.MINUTE) + ":" + cl.get(Calendar.SECOND);

How to change milliseconds to yyyy-MM-dd'T'HH:mm:ssS format?

you have seconds not milliseconds you should multipy your seconds * 1000

Android converting the time in milliseconds

To understand what's happening:

• Calendar.getInstance() creates a Calendar with the current date/time in the JVM default timezone
• You set the hour, minutes and seconds (to 01:30:00 I suppose)
• You call getTimeInMillis(), that returns the number of milliseconds since unix epoch (1970-01-01T00:00Z)

Then you use this milliseconds value with TimeUnit, but that's not what you need. TimeUnit will treat the number of milliseconds as an amount of time, but what you need is a time of the day:

• a time of the day is a specific moment in a day, such as "10 AM" or "05:30 PM".
• an amount of time is just, well, an amount of elapsed time, such as "10 minutes and 45 seconds", or "2 years, 4 months, 5 days and 17 hours", but it's not attached to a specific point in time ("10 minutes relative to what?"); it's just the amount of time, by itself.

Although both concepts might use the same words ("hours", "minutes", "seconds", etc), they're not the same thing.

TimeUnit deals with amounts of time, so it does conversions like "1000 seconds is equivalent to how many minutes?".

Example: TimeUnit.MILLISECONDS.toHours(value) returns the number of hours equivalent to value milliseconds (not the time of the day). As the value you're using is the result of getTimeInMillis(), you're getting the total number of hours since January 1970.

By using the result of getTimeInMillis() (which represents a specific point in time) with TimeUnit, you're misusing the value, treating like it was an amount of time.

To format a date, you can use a SimpleDateFormat:

Calendar mycalendar = Calendar.getInstance();
mycalendar.set(Calendar.HOUR_OF_DAY, 1);
mycalendar.set(Calendar.MINUTE, 30);
mycalendar.set(Calendar.SECOND, 0);

// format: hour:minute:second
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss");
String hms = sdf.format(mycalendar.getTime()); // 01:30:00

With this, hms will have the value 01:30:00. Check the javadoc to know what the format HH:mm:ss means, so you can change it in case you need a different format (If you want just 01:30, for example, the format will be HH:mm).

Java new Date/Time API

The old classes (Date, Calendar and SimpleDateFormat) have lots of problems and design issues, and they're being replaced by the new APIs.

In Android you can use the ThreeTen Backport, a great backport for Java 8's new date/time classes. To make it work, you'll also need the ThreeTenABP (more on how to use it here).

First you create a org.threeten.bp.LocalTime (a class that represents a time of the day), then you format it with a org.threeten.bp.format.DateTimeFormatter:

// create time for 01:30
LocalTime time = LocalTime.of(1, 30);
// format: hour:minute:second
DateTimeFormatter fmt = DateTimeFormatter.ofPattern("HH:mm:ss");
String hms = fmt.format(time);
System.out.println(hms); // 01:30:00

Also, check the javadoc for all available formats.

android convert date string to time in milliseconds

Use MM for month.

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

and to get Time use Date.getTime() method.

How to convert milliseconds to date in SQLite

One of SQLite's supported date/time formats is Unix timestamps, i.e., seconds since 1970.
To convert milliseconds to that, just divide by 1000.

Then use some date/time function to get the year and the month:

SELECT strftime('%Y-%m', MillisField / 1000, 'unixepoch') FROM MyTable
