Question about Games That Contain Day and Night Cycles

Hello, I have a question in regards to games that contain day and night cycles. What would be a good starting time? What I mean is, a player joins a brand new server and nobody is in the sever but them. What time should it be upon their connection to the server?

Maybe between 7:00 - 12:00,but if you want the exact time(Starting the loop of the clock)it would be 00:00.
