The country that is "most ahead in time" depends on what you mean by "ahead in time."
- If you're asking about the country with the latest time zone, then it's Kiribati, which has the most advanced time zone in the world, UTC+14.
- If you're asking about the country with the most advanced technology, then it's difficult to definitively say. Different countries lead in different areas, such as China in artificial intelligence or South Korea in mobile technology.
It's important to define your question more clearly to get a specific answer.
