input

  <div class="input-field col s12 m4">
  <input type="text" id="hora_entrada" class="timepicker" 
   name="hora_entrada"/>
   <label for="cuentas" class="black-text ">Hora de Entrada:</label>
  </div>

  <div class="input-field col s12 m4">
 <input type="text" id="hora_salida" class="timepicker" name="hora_salida"/>

 </div>




  <!--Import jQuery before materialize.js-->
  <script type="text/javascript" src="../js/jquery-3.2.1.min.js"></script>
  <script type="text/javascript" src="../js/materialize.min.js"></script>
  <script type="text/javascript" src="../js/jquery.min.js"></script>


  <!--  Scripts-->
    <script>
    $(document).ready(function() { 
    $('select').material_select();
    $(".button-collapse").sideNav();
    $(".dropdown-button").dropdown();
    $('.timepicker').pickatime({
          default: 'now', // Set default time: 'now', '1:30AM', '16:30'
          fromnow: 0,       // set default time to * milliseconds from now (using with default = 'now')
         twelvehour: false, // Use AM/PM or 24-hour format
         donetext: 'OK', // text for done-button
         cleartext: 'Clear', // text for clear-button
         canceltext: 'Cancel', // Text for cancel-button,
         container: undefined, // ex. 'body' will append picker to body
         autoclose: false, // automatic close timepicker
         ampmclickable: true, // make AM PM clickable
         aftershow: function(){} //Function for after opening timepicker
                 });

                 });
           </script>
