JSF default timezone and date pattern

By default JSF using GMT timezone to convert the date into display format. I did Google search about this issue, found no simple solution to solve this problem.

Here is a simple solution where you can provide your custom date time converter. I like this solution because it fixes GMT date/time issue across the application.

1) Write a new custom converter by extending existing DateTimeConverter class.

package com.company.project.converter;

import java.util.TimeZone;

import javax.faces.convert.DateTimeConverter;

public class CustomDateTimeConverter extends DateTimeConverter {

public CustomDateTimeConverter() {
// here you can set your custom date pattern for your project
// setPattern("M/d/yy");


Bind your new converter as default converter for object of type java.util.Date

    You talk about the pattern. But, sometimes, the date is simply dd/MM/yyy (no time), and sometime have time. How we can handle it?

    Using jsf 1.2 and icefaces 1.8.2_7, I had to register the custom converter using id “javax.faces.DateTime” in order to enable it with .

  10. right using javax.faces.DATETIMECONVERTER_DEFAULT_TIMEZONE_IS_SYSTEM_TIMEZONE define timeZone, but who define the format unused tag f:convertDateTime, can you define this in web.xml a configuration?
