LogRecord setMillis() method in Java with Examples

The setMillis() method of java.util.logging.LogRecord is used to set the event time in LogRecord.This event time has unit in MilliSeconds since 1970.
Syntax:

public void setMillis(long millis)

Parameters: This method accepts millis as parameter which is event time in milli-seconds since 1970
Return: This method returns nothing.
Below programs illustrate setMillis() method: 
Program 1:

Java

// Java program to illustrate setMillis() method

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Level;
import java.util.logging.LogRecord;

public class GFG {

    public static void main(String[] args)
    {

        // Create LogRecord object
        LogRecord logRecord = new LogRecord(
            Level.parse("800"),
            "Hi Logger");

        // set event time
        logRecord.setMillis(999999999900L);

        // get event time and convert it into date
        DateFormat simple
            = new SimpleDateFormat(
                "dd MMM yyyy HH:mm:ss:SSS Z");

        Date result
            = new Date(logRecord.getMillis());

        System.out.println("Event Time "
                           + simple.format(result));
    }
}

Output:

Event Time 09 Sep 2001 01:46:39:900 +0000

Program 2:

Java

// Java program to illustrate setMillis() method

import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.logging.Level;
import java.util.logging.LogRecord;

public class GFG {

    public static void main(String[] args)
    {

        // Create LogRecord object
        LogRecord logRecord = new LogRecord(
            Level.parse("800"),
            "GFG Logger");

        // set event time
        logRecord.setMillis(9632736138L);

        // get event time and convert it into date
        DateFormat simple
            = new SimpleDateFormat(
                "dd MMM yyyy");

        Date result
            = new Date(logRecord.getMillis());

        System.out.println("Event Date: "
                           + simple.format(result));
    }
}

Output:

Event Date: 22 Apr 1970
