Which command is used to manually set the date in the system?

The command that is used to manually set the date in the system is typically structured in a specific format that aligns with standard command conventions. In this case, the option specifying the date format as "DD-MMM-YYYY" represents a clear and common method for indicating the day, month (abbreviated), and year. This command format allows users to specify the exact date they wish to set on the system, which is crucial for ensuring accurate timekeeping and scheduling in various applications and processes.

The use of specific abbreviations for the months makes it easier for the system to interpret the input correctly, as opposed to using numeric representations that could lead to confusion, especially in cases where date formats vary by region. Therefore, this option accurately describes the method of setting the date manually in a straightforward and commonly recognized way, making it the correct choice for this question.
