Final answer:
The /t switch displays the current time or date in a command line prompt without prompting the user to set new ones. For digital cameras, the date/time settings can be found and adjusted within the camera's Settings menu.
Step-by-step explanation:
The function of the /t switch in the command extension when typing 'Time /t' or 'Date /t' in the command line prompt is to display the current time or date, respectively, in a terminal or command prompt window without prompting the user for a new time or date to set. When you execute either command with the /t switch, the system outputs the current time or current date only and then returns you to the command prompt.
To set the date/time for a digital camera, you would typically locate and press the menu button on the camera, navigate to Settings, and locate the options for setting/changing the date/time. From there, you would ensure the date/time is set correctly. This process may vary depending on the camera model.
