Undefined class DateTime in PHPStorm

问题

I want to use class DateTime but PHPStorm says me that "Undefined class DateTime" and my PHP version is 5.5.9-1. I'm using PHPStorm version 2016.1 and i'm working with Yii2 framework (if it'll give you any useful information). So how can i use with correct lint default PHP classes?

You need to use backslash \DateTime or add use DateTime;
