Definition

While and within that time are both phrases used to indicate a specific period or duration. While is often used to show a contrast or simultaneous action, while within that time is used to specify a time frame or limit within which something must be done or completed.

Usage

While is commonly used in sentences to introduce a contrasting idea or action. For example, "I like to read while I drink my morning coffee." Within that time, on the other hand, is used to specify a time frame or deadline. For instance, "You must complete the assignment within that time frame."

Duration

While can refer to a period of time that is ongoing or continuous. It does not necessarily have a specific end point. Within that time, however, implies a specific time frame or limit within which something must be done or completed. It indicates a duration that has a clear beginning and end.

Clarity

While can sometimes be ambiguous in terms of the exact time frame being referred to. It can be used in a more general sense without specifying a specific duration. Within that time, on the other hand, provides a clear indication of the time frame or deadline that is being referred to, making it more precise and specific.

Examples

While I was studying for my exam, my roommate was watching TV. Within that time frame, I had to finish the entire textbook. While he was at work, she cleaned the entire house. Within that time, she managed to finish all her chores.
