Which country uses CET?

Could you please clarify which country utilizes the Central European Time (CET) as its standard time zone? CET is a common time zone observed in various parts of Europe, particularly in central and eastern regions. I'm curious to know if there's a specific country you're referring to, or if you're seeking a general overview of the countries that adhere to this time zone. It would be helpful to have more context in order to provide a precise answer.
