To understand the context and give a helpful answer, please tell me more about:
* What are you referring to by "Master Standing Orders"?
* Are you talking about medical standing orders, military standing orders, or something else entirely?
* What do you mean by "Night"?
* Are you asking about the importance of night orders in a specific context (e.g., medical, military, or other)?
* Or are you asking about the importance of the night time period itself in a specific context?
Once I understand your query, I can provide a more precise and helpful response.
