It seems like you're asking about a situation where the time is somehow "twice" when an object is undergoing unit acceleration. However, the question is a bit ambiguous. To understand what you're asking, I need more context.

Could you please clarify your question by providing some additional information? For example:

* What do you mean by "twice the time"? Are you referring to:

* The time it takes for the object to reach a certain velocity?

* The time it takes for the object to travel a certain distance?

* Something else entirely?

* What is "unit acceleration"? Are you referring to:

* An acceleration of 1 m/s²?

* An acceleration of 1 ft/s²?

* Some other unit of acceleration?

Once you provide more information, I can help you understand the relationship between time, acceleration, and other relevant variables.
