Conversion between String and Date in client-side GWT

Using SimpleDateFormat is a standard way to do String <-> Date conversion in Java.

But this class is not present in GWT JRE Emulation library so we can't use it in GWT client-side code.

What is standard/recommended way of doing this conversion, then?

As given an example in Date Time Format, this may be helpful. 

public class DateTimeFormatExample implements EntryPoint {

  public void onModuleLoad() {
    Date today = new Date();

    // prints Tue Dec 18 12:01:26 GMT-500 2007 in the default locale.
    GWT.log(today.toString(), null);

    // prints 12/18/07 in the default locale
    GWT.log(DateTimeFormat.getShortDateFormat().format(today), null);

    // prints December 18, 2007 in the default locale
    GWT.log(DateTimeFormat.getLongDateFormat().format(today), null);

    // prints 12:01 PM in the default locale
    GWT.log(DateTimeFormat.getShortTimeFormat().format(today), null);

    // prints 12:01:26 PM GMT-05:00 in the default locale
    GWT.log(DateTimeFormat.getLongTimeFormat().format(today), null);

    // prints Dec 18, 2007 12:01:26 PM in the default locale
    GWT.log(DateTimeFormat.getMediumDateTimeFormat().format(today), null);

    // A custom date format
    DateTimeFormat fmt = DateTimeFormat.getFormat("EEEE, MMMM dd, yyyy");
    // prints Monday, December 17, 2007 in the default locale
    GWT.log(fmt.format(today), null);
  }
}
