Java Timestamp

Last Updated : 17 Mar 2025

Timestamp provides formatting and parsing operations to support JDBC escape syntax. It also adds the ability to hold the SQL TIMESTAMP fractional seconds value.

Methods

Methods	Description
after()	Returns Boolean value true if this Timestamp object comes later than given Timestamp object.
before()	Returns Boolean value true if this Timestamp object comes earlier than given Timestamp object.
compareTo()	Compares this Timestamp object to the given Timestamp object or to the given date object
equals()	Returns a Boolean value true if this Timestamp object is equal specified object or to the given Timestamp object .
from()	Obtains an instance of Timestamp from an Instant object
getNanos()	Fetches the Timestamp object's nanos value
getTime()	Returns the number of milliseconds since January 1, 1970, 00:00:00 GMT
hashCode()	Returns a hash code value for this object
setNanos()	Sets a nanos value for the specified integer value
setTime()	Sets this class's object to indicate a point in time (milliseconds) after January 1, 1970 00:00:00 GMT
toInstant()	Coverts the Timespan object to an Instant which represents the same point on the time-line as this Timestamp
toLocalDateTime()	Converts this Timespan object to a LocalDateTime which represents the same date-time value as this Timestamp
toString()	Converts the Timespan object in JDBC timestamp escape format
valueOf()	Converts the string object to Timestamp value or obtains an instance of Timestamp from a LocalDateTime object.

Example 1

import java.sql.Timestamp;
import java.time.Instant;
public class JavaTimestampFromExample_1 {
    public static void main(String[] args) {
        //from() method Obtains an instance of Timestamp from an Instant object
       Timestamp instant= Timestamp.from(Instant.now());
        System.out.println("1. from() method will return "+instant);
        // valueOf() method returns a Timestamp value corresponding to the given string
        String str="2018-09-01 09:01:15";
        Timestamp timestamp= Timestamp.valueOf(str);
        System.out.println("2. value of Timestamp : "+timestamp);
        //getNanos() method gets the Timestamp obejct's nanos value
        Integer val=timestamp.getNanos();
        System.out.println("3. Fractional seconds component : "+val);
        Timestamp ts2 = Timestamp.valueOf("2018-09-01 09:01:16");
        //before() returns Boolean value true if this ts1 comes earlier than given ts2
        System.out.println("4. Boolean value returned : "+timestamp.before(ts2));
    }
}

Output:

1. from() method will return 2018-09-06 12:42:53.885
2. value of Timestamp : 2018-09-01 09:01:15.0
3. Fractional seconds component : 0
4. Boolean value returned : true

Example 2

import java.sql.Timestamp;
import java.time.Instant;
public class JavaTimespanExample2 {
    public static void main(String[] args) {
        Timestamp ts1 = Timestamp.valueOf("2018-09-01 09:01:15");
        System.out.println("Timestamp : "+ts1);
        // getTime() method returns the number of milliseconds
        Long val=ts1.getTime();
        System.out.println("1. Milliseconds : "+val);
        //hashCode() method returns the hash code for this object.
        Integer val1=ts1.hashCode();
        System.out.println("2. Hash code : "+val1);
        // setNanos() method sets nanos value for the specified integer value.
        ts1.setNanos(54647);
        System.out.println("3. Timestamp after setting nanos : " + ts1);
        // toInstant() method returns an Instant which represents the same point on the time-line as this Timestamp
        Instant instant = ts1.toInstant();
        System.out.println("4. Instant Timespan : " + instant);
    }
}

Output:

Timestamp : 2018-09-01 09:01:15.0
1. Milliseconds : 1535772675000
2. Hash code : -1825617187
3. Timestamp after setting nanos : 2018-09-01 09:01:15.000054647
4. Instant Timespan : 2018-09-01T03:31:15.000054647Z
