How it's used
Carries a formal, professional tone that makes it suitable for business announcements, news reports, or official invitations. It functions as a direct, more sophisticated substitute for the everyday term 到時. Using it in casual conversation with friends can sound overly stiff or pretentious.
Examples
This exhibition will be held next month; everyone is welcome to visit then.
Will you be attending that meeting at the appointed time?

Common mistake
Learners often mistakenly use it as a noun to mean 'the time' itself, but it is strictly an adverbial phrase referring to a future point in time. It cannot be used as the subject or object of a sentence.
