body: <p>Is it possible to set start time for PrimeFaces clock widget?
  I know about Analog Clock from PrimeFaces Extensions, but I need digital clock with this option.
  I have tried to override javascript method for this clock, but it doesn't work.</p>
  
  <pre><code>  PrimeFaces.widget.Clock = PrimeFaces.widget.BaseWidget.extend({
  
      init: function(cfg) {
          this._super(cfg);
  
          this.cfg.value = 1430304817141;
          this.current = this.isClient() ? new Date() : new Date(this.cfg.value);
          var $this = this;
  
      },
  
      isClient: function() {
          return this.cfg.mode === 'client';
      },
  
  });
  </code></pre>
