Timestamp method for Behat

FeatureContext.php

<?php

use Behat\Behat\Context\ClosuredContextInterface,
    Behat\Behat\Context\TranslatedContextInterface,
    Behat\Behat\Context\BehatContext,
    Behat\Behat\Exception\PendingException;
use Behat\Gherkin\Node\PyStringNode,
    Behat\Gherkin\Node\TableNode;


/**
 * Features context.
 */
class FeatureContext extends BehatContext
{
    /**
     * Initializes context.
     * Every scenario gets it's own context object.
     *
     * @param array $parameters context parameters (set them up through behat.yml)
     */
    public function __construct(array $parameters)
    {
        // Initialize your context here
    }

    /**
     * @Transform /^(.*\(timestamp\).*)$/
     */
    public function timestamp($string)
    {
      $pattern = '/\(timestamp\)/';
      $time = date('i.s');
      $timestamp = preg_replace($pattern, $time, $string);

      return $timestamp;
    }
}

If this is tabular data will it change the value that i printed in the log-output ?

Or will the log output still show "timestamp"
