I'm trying to get wordpress post by date and time, for example from 02/01/2014 to 02/05/2014 and time 17:10, somebody knows?

thanks for the help

The WP_Query class can fulfill this. Just set up a new query, passing in the appropriate arguments:

$args = array(
    'date_query' => array(
         // limit to between these dates
        array(
            'after'     => '2014-02-01',
            'before'    => '2014-02-05', //remove this line if no upper limit
            'inclusive' => true,
            ),
         // limit to posts before 17:10 (not tested)
        array(
            'hour'      => 17,
            'minute'    => 10,
            'compare'   => '<=',
            ),
         // limit to posts after 08:30
        array(
            'hour'      => 08,
            'minute'    => 30,
            'compare'   => '>=',
            ),
        ),
    'posts_per_page' => -1,
    );
$my_date_query = new WP_Query( $args );

Then run your loop using the query object you just instatiated:

<?php if ( $my_date_query->have_posts() ) : ?>

  <!-- the loop -->
  <?php while ( $my_date_query->have_posts() ) : $my_date_query->the_post(); ?>
    <h2><?php the_title(); ?></h2>
  <?php endwhile; ?>
  <!-- end of the loop -->

  <?php wp_reset_postdata(); ?>

<?php else:  ?>
  <p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>

The date parameters section gives a good overview of the types of post queries you can create: http://codex.wordpress.org/Class_Reference/WP_Query#Date_Parameters

NB Don't use query_posts . From the codex :

query_posts() is overly simplistic and problematic way to modify main query of a page by replacing it with new instance of the query. It is inefficient (re-runs SQL queries) and will outright fail in some circumstances
