Magento Change Pager Phtml Custom Module

In you block of custom module, for e.g.In my case,  Netgo_Userstatus_Block_Userstatus_List

Just Use the blow code in _prepareLayout() function

  protected function _prepareLayout()
{
        parent::_prepareLayout();
        $pager = $this->getLayout()->createBlock(
            'page/html_pager',
            'netgo_userstatus.userstatus.html.pager'
        )->setTemplate('page/html/newsfeed_pager.phtml')
        ->setCollection($this->getUserstatuss());
        $this->setChild('pager', $pager);
        $this->getUserstatuss()->load();
        return $this;
    }

The Red colored is the extra code that I have added, you can define your phtml file for the pager.

Magento admin change default page size of grid

You have to modify two files for that: Grid.php and Grid.phtml,
Below are the details of files:

In Admin Block File:
/public_html/app/code/core/Mage/Adminhtml/Block/Widget
Grid.php

Search for $_defaultLimit in the file and change the value according to your choice.
protected $_defaultLimit    = 75;

PHTML File:
app/design/adminhtml/default/default/template/widget
grid.phtml

Add your option in the select box.

<select name="<?php echo $this->getVarNameLimit() ?>" onchange="<?php echo $this->getJsObjectName() ?>.loadByElement(this)">
<option value="20"<?php if($this->getCollection()->getPageSize()==20): ?> selected="selected"<?php endif; ?>>20</option>
<option value="30"<?php if($this->getCollection()->getPageSize()==30): ?> selected="selected"<?php endif; ?>>30</option>
<option value="50"<?php if($this->getCollection()->getPageSize()==50): ?> selected="selected"<?php endif; ?>>50</option>
<option value="75"<?php if($this->getCollection()->getPageSize()==75): ?> selected="selected"<?php endif; ?>>75</option>
<option value="100"<?php if($this->getCollection()->getPageSize()==100): ?> selected="selected"<?php endif; ?>>100</option>
<option value="200"<?php if($this->getCollection()->getPageSize()==200): ?> selected="selected"<?php endif; ?>>200</option>
</select>

I have added 75 as additional page size, It will be default pagesize too.

Facebook page feed time issue

I was implementing facebook page feed for one of my client, the feeds were appearing correct but time was different, actually it was a timezone issue, you have to convert facebook time to local timezone, and to do this i found the perfect way.

step1.
Download and include the js file into your script.

step2:

use below code to determine the client timezone:

<script type="text/javascript">
    jQuery(document).ready(function() {
       var timezone = jstz.determine();
var timezonename = timezone.name();  
    });
</script>
