How to get (format) date and time from mill seconds in Java?
The java.text.SimpleDateFormat class is used to format and parse a string to date and date to string.
One of the constructors of this class accepts a String value representing the desired date format and creates SimpleDateFormat object.
To format milli seconds to date −
- Create the format string as dd MMM yyyy HH:mm:ss:SSS Z.
- The Date class constructor accepts a long value representing the milliseconds as a parameter and creates a date object.
- Finally format the date object using the format() method.
Example
import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;
public class Sample {
public static void main(String args[]) throws ParseException {
long msec = 3550154;
//Instantiating the SimpleDateFormat class
SimpleDateFormat dateformatter = new SimpleDateFormat("dd MMM yyyy HH:mm:ss:SSS Z");
//Parsing the given String to Date object
Date date = new Date(msec);
System.out.println("Date value: "+dateformatter.format(date));
}
}Output
Date value: 01 Jan 1970 06:29:10:154 +0530
Example
import java.util.Calendar;
import java.util.Date;
public class Sample {
public static void main(String args[]) {
Calendar calendar = Calendar.getInstance();
long msec = calendar.getTimeInMillis();
Date obj = new Date(msec);
System.out.println(obj);
}
}Output
