Are you asking how many hours people work, or at what times of the day people work? From the question, this is not really clear, although the former seems more likely. Furthermore, no indication of intent or reason for asking was given. For example, someone may want to know whether there are regional trends among HNer workloads. In that case, it would be useful if participants included whether the job were local, remote, contract, and or employment.
