Plugin's time is two hours less?

Hello, friend. First of all, congratulations on creating this plugin. To me, it works flawlessly, even in the latest version of WordPress.

However, when trying to set an expiration date, I noticed that I had to set it to two hours less than the time I wanted in order for it to work. For instance, right now is 17:33, but if I set to to expire on 17:34, it will stay published until 19:34.

At first, I thought it was a problem with the time zone, but couldn’t find anywhere to change this on the settings page. Then I thought it could be a problem with my XAMPP server, but my phpinfo() says that the timezone is Berlin (which I think is correct for Madrid UTC+1).

So, what could be causing the problem?

thank you so much for your time and for your hard work.
