It may happen if we try to load contact form through a static block or cms .

When you  do so make sure that you have included ‘  form_action=”/contacts/index/post ‘ .ie The code will

be

{{block type=”core/template” name=”contactForm” form_action=”/contacts/index/post” template=”contacts/form.phtml”}}

But when we submit the contact form , the page will be redirected to the original contact form

“magento/contacts/ ” after sending the mail . To fix that we should  override the function “postAction” in

/var/www/html/app/code/core/Mage/Contacts/controllers/IndexController.php and edit the code

“$this->_redirect(‘*/*/’);” at line number 113 with the page url . ie for eg :

“$this->_redirect(‘contatcs’)

Try by replacing

<?php getLayout()->getMessagesBlock()->getGroupedHtml(); ?>

with

<?php

getLayout()->getMessagesBlock()->setMessages(Mage::getSingleton(‘customer/session’)->getMessages(true)); ?>
getLayout()->getMessagesBlock()->getGroupedHtml();

?>

1) Change the directory to magento installation
2  cd appcodecoreMageContactscontrollers
3) vi IndexController.php
4) Search for Mage::getSingleton(‘customer/session’)->addSuccess(Mage::helper(‘contacts’)->__(‘Your inquiry was submitted and will be responded to as soon as possible. Thank you for contacting us.’)) and edit the text

You can change the time zone from the admin panel

Go  to System > Configuration > General  >  General > Locale Options and edit the field “Timezone “
