Question

我有一个使用DateTime::createFromFormat的函数，它产生了一些非常奇怪的行为。它正在改变解析后的字符串。时区以date_default_timezone_set('America/Chicago');声明。它运行在Ubuntu 12.04上，Apache 2.2.22和PHP 5.4.25。功能是：

public function getTimeDiff()
{
    \Zend\Debug\Debug::dump($this->start);
    $startDateTime = \DateTime::createFromFormat('Y-m-d H:m:s.u',$this->start);
    $startTimestamp = $startDateTime -> getTimestamp();
    \Zend\Debug\Debug::dump($startDateTime);

    \Zend\Debug\Debug::dump($this->stop);
    $stopDateTime = \DateTime::createFromFormat('Y-m-d H:m:s.u',$this->stop);
    $stopTimestamp = $stopDateTime -> getTimestamp();
   \Zend\Debug\Debug::dump($stopDateTime);

    $diffInSeconds = $stopTimestamp - $startTimestamp;

    return $diffInSeconds;
}

调试信息如下所示：

string '2014-05-02 08:00:00.000' (length=23)
object(DateTime)[426]
  public 'date' => string '2013-12-02 08:00:00' (length=19)

  public 'timezone_type' => int 3
  public 'timezone' => string 'America/Chicago' (length=15)

知道造成这种变化的原因是什么吗？我希望它显而易见，无论出于何种原因我都无法看到。

您的格式出错：Y-m-d H：m：s.u您将m用作月份和分钟。使用我几分钟。 -phpisuber01
