The greeting that you leave on your phone in the form of a voice mail can be very important as it is the first contact that anyone calling has with you or the company that you work for. Therefore it is important that your voicemail greeting is drafted in such a manner that it does not make the caller squirm in embarrassment, or even raise their eyebrows in sheer wonder. Proper voicemail etiquette demands that a good voicemail message convey information like whom the caller is calling, where they are, when the caller can expect to be called back, and what to do if the call that is being made is of an urgent nature.
17. "Hello! You've gotten the voicemail of [your name]. Leave your name, contact info, and the answer to the eternal question ‘Which came first, the chicken or the egg?' Anyone who gets it right will receive a call back."

Most callers expect their call to be answered. Once they realize that your office is currently closed, the most important piece of information they probably want to know is your standard business hours.
