To get the current timestamp in Java :


Timestamp timestamp = new Timestamp(System.currentTimeMillis());
//2016-11-16 06:43:19.77

Here are two Java examples to show you how to get current timestamps in Java. (Updated with Java 8)

1. java.sql.Timestamp

Two methods to get the current java.sql.Timestamp

TimeStampExample.java

package com.mkyong.date;

import java.sql.Timestamp;
import java.text.SimpleDateFormat;
import java.util.Date;

public class TimeStampExample {

    private static final SimpleDateFormat sdf = new SimpleDateFormat("yyyy.MM.dd.HH.mm.ss");

    public static void main(String[] args) {

        //method 1
        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        System.out.println(timestamp);

        //method 2 - via Date
        Date date = new Date();
        System.out.println(new Timestamp(date.getTime()));

        //return number of milliseconds since January 1, 1970, 00:00:00 GMT
        System.out.println(timestamp.getTime());

        //format timestamp
        System.out.println(sdf.format(timestamp));
        
    }

}

Output


2016-11-16 06:43:19.77
2016-11-16 06:43:19.769
1479249799770
2016.11.16.06.43.19

2. java.time.Instant

In Java 8, you can convert java.sql.Timestamp to the new java.time.Instant

InstantExample.java

package com.mkyong.date;

import java.sql.Timestamp;
import java.time.Instant;

public class InstantExample {
    
    public static void main(String[] args) {

        Timestamp timestamp = new Timestamp(System.currentTimeMillis());
        System.out.println(timestamp);

        //return number of milliseconds since January 1, 1970, 00:00:00 GMT
        System.out.println(timestamp.getTime());

        // Convert timestamp to instant
        Instant instant = timestamp.toInstant();
        System.out.println(instant);

        //return number of milliseconds since the epoch of 1970-01-01T00:00:00Z
        System.out.println(instant.toEpochMilli());

        // Convert instant to timestamp
        Timestamp tsFromInstant = Timestamp.from(instant);
        System.out.println(tsFromInstant.getTime());

    }

}

Output


2016-11-16 06:55:40.11
1479250540110
2016-11-15T22:55:40.110Z
1479250540110
