Change K2 Date Format

Hi, this is just a simple request...

The K2 articles on this template uses date format >>> 'M j'

I would like to change the K2 article date format into this >> 'd F Y | H:i'

I tried to look the code but I'm not sure which file is it... can you help with this?

Thank you very much...

Hi,
if we talk about K2 item view :
templates\gk_bluap\html\com_k2\templates\default\item.php

line 50

<li class="itemDate"><time datetime="<?php echo JHtml::_('date', $this->item->created, JText::_(DATE_W3C)); ?>"><?php echo JHTML::_('date', $this->item->created, JText::_('F j, Y')); ?></time></li>

Ok, thank you Oscar...
problem fixed...

In others files in this same folder you have to search in you want to change also in blog view etc.
