Yes, it is common. "It is high time to do this/something." Hope this helps! :)

I would say “It’s high time that…” + noun+verb is more common where I am from.

Very common everywhere I've lived in the U.S. The expression is hundreds of years old. It originated in England, not the U.S. Shakespeare used it. When you say "it's high time we do something", it means we should have already done it.

In the US, "it's high time" is quite common. It means "it's overdue," "it should have happened long ago." Sometimes a quick way to check current usage is to do a search in Google News. When I do this, I quickly find many examples: "It's high time Biden lifts the COVID testing requirement for international travelers" "Docs: It's High Time to Declare Gun Violence a Public Health Emergency" "Editorial: It's high time to end legacy admissions" "It's High Time We Acknowledged That Plastic Recycling Is a Myth" "It's high time to legalize cannabis"
