Well, first, think about how the time affects the plot. Is it a deadline, a significant moment? Then, describe it vividly. Maybe say 'It was 3 o'clock in the afternoon, and the sun was beating down.' That gives a clear image. Also, use time transitions smoothly to keep the story flowing.
The key is to make the time relevant and interesting. For example, 'At midnight, when the world was asleep, the adventure began.' This creates a sense of mystery. And don't forget to be consistent with the time throughout the story board.
You need to be clear and specific. Mention the exact hour, minute, and maybe even the second if it's crucial for the story. Also, consider using visual cues like clocks or shadows to imply the time.
