Just like this:

<?php Pjax::begin(); ?>

<h1>Current time: <?= $time ?></h1>
<?php Pjax::end(); ?>

it worked!

I think this can solve your problem.

<span class="my-btn  btn btn-lg btn-danger">refresh</span>
<a href="javascript:function() { return false; }" class="my-btn btn btn-lg btn-primary"> refresh a</a>

<?php

$this->registerJs(
   '$("document").ready(function(){ 
        $(".my-btn").on("click", function() {
            $.pjax.reload({container:"#greet"});
        });
    });'
);
?>
<?php yii\widgets\Pjax::begin(['id'=>'greet']); ?>

<h1>Current time: <?= time() ?></h1>
<?php yii\widgets\Pjax::end(); ?>

PJAX has timeout option. If PJAX not obtain AJAX response during this timeout, it will perform full page reload. Use following JS snippet:

$.pjax.defaults.timeout = false;       // For JS use case yor should manual override default timeout.
$.pjax.reload({container: '#pjaxId'});

or more short snippet:

$.pjax.reload('#pjaxId', {timeout : false});

Moreover in my projects I use overrided version of Pjax:

/**
 * Custom Pjax with incremented timeout.
 * JS for Pjax updating:
 *  <code>
 *      $.pjax.defaults.timeout = false;             // For JS use case yor should manual override default timeout.
 *      $.pjax.reload({container: '#pjaxId'});
 *
 *      // OR
 *      $.pjax.reload('#pjaxId', {timeout : false});
 *
 *      // OR for gridview with search filters
 *      $('.grid-view').yiiGridView('applyFilter'); // Thats true only if you have search Filters
 *  </code>
 *
 * Note: In more cases ID of widget should be static, because widgetId is autoincremented and browser version of page may be not up-to-date.

class Pjax extends \yii\widgets\Pjax
{
    /**
     * @var int Timeout {@link \yii\widgets\Pjax::$timeout}.
     *          For JS use case yor should manual override defaults (  $.pjax.defaults.timeout = false;  ).
     */
    public $timeout = 30000;
}
