Imports the clock module to retrieve the current time. By default, the time is displayed in the format "h:mm a" (e.g., 3:45 PM). You can customize the format by passing a different time format string if required.

Example formats:

• "h:mm a" → 3:45 PM (default)

• "HH:mm" → 15:45 (24-hour format)

• "hh:mm:ss a" → 03:45:00 PM
