  I've used the bootstrap up, and used the moment.js,but it still doesn't work.
  Please give some help , thanks !</p>
  
  <p><strong>my main py</strong></p>
  
  <pre><code>from flask.ext.bootstrap import Bootstrap
  from flask.ext.moment import Moment
  from flask import request
  from datetime import datetime
  
  app = Flask(__name__)
  bootstrap=Bootstrap(app)
  moment=Moment(app)
  
  @app.route('/')
  def index():
      return render_template('index.html',current_time=datetime.utcnow())
  </code></pre>
  
  <p><strong>This is my base.html which extends from the bootstrap</strong></p>
  
  <pre><code>{% extends "bootstrap/base.html" %}
  {%block head%}
  {{super()}}
  &lt;link rel='shortcut icon' href="{{url_for('static',filename='favicon.ico')}}" type='image/x-icon'&gt;
  &lt;link rel='icon' href="{{url_for('static',filename='favicon.ico')}}" type="image/x-icon"&gt;
  {% block scripts %}          #Here I use the bootstrap
  {{ super() }}                 #But I dont' whether it works or not
  {{ moment.include_moment() }}
  {% endblock %}
  {%endblock%}
  
  {% block title %}Flasky{% endblock %}
  
  {% block navbar %}
      &lt;div class="navbar navbar-inverse" role="navigation"&gt;
      &lt;div class="container"&gt;
      &lt;div class="navbar-header"&gt;
      &lt;button type="button" class="navbar-toggle"
          data-toggle="collapse" data-target=".navbar-collapse"&gt;
          &lt;span class="sr-only"&gt;Toggle navigation&lt;/span&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;
          &lt;span class="icon-bar"&gt;&lt;/span&gt;
      &lt;/button&gt;
  &lt;a class="navbar-brand" href="/"&gt;Flasky&lt;/a&gt;
      &lt;/div&gt;
  &lt;div class="navbar-collapse collapse"&gt;
      &lt;ul class="nav navbar-nav"&gt;
      &lt;li&gt;&lt;a href="/"&gt;Home&lt;/a&gt;&lt;/li&gt;
      &lt;/ul&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  &lt;/div&gt;
  {% endblock %}
  {% block content %}
      &lt;div class="container"&gt;
  {% block page_content %}{% endblock %}
      &lt;/div&gt;
  {% endblock %}
  </code></pre>
  
  <p><strong>The last is the index.html</strong></p>
  
  <pre><code>&lt;p&gt;The local date and time is {{moment(current_time).format('LLL')}}.&lt;/p&gt;
  &lt;p&gt;That was {{moment(current_time).fromNow(refresh=True)}}&lt;/p&gt;
