    public static void main(String[] args)

        /*

         * Instant MAX defines the maximum supported Instant,

         * '1000000000-12-31T23:59:59.999999999Z' is the value.

         */

        Instant instant = Instant.MAX;

        System.out.println("Max = "+instant);

        System.out.println("Max EpochSecond = "+instant.getEpochSecond());

        /*

         * Instant MIN defines the minimum supported Instant,

         * '-1000000000-01-01T00:00Z'.

         */

        instant = Instant.MIN;

        System.out.println("Min = "+instant);

        System.out.println("Min EpochSecond = "+instant.getEpochSecond());

        /*

         * Instant EPOCH defines the constant for the

         * 1970-01-01T00:00:00Z epoch instant.

         */

        instant = Instant.EPOCH;

        System.out.println("EPOCH = "+instant);

        System.out.println("EPOCH EpochSecond = "+instant.getEpochSecond());

    }

}

Output

Max = +1000000000-12-31T23:59:59.999999999Z

Max EpochSecond = 31556889864403199

Min = -1000000000-01-01T00:00:00Z

Min EpochSecond = -31557014167219200

EPOCH = 1970-01-01T00:00:00Z

EPOCH EpochSecond = 0
