This widget consists of an analogue clock. The clock has day and night style displays which are used depending on the time. The period interpreted as day by the clock is controlled by a pair of constants kStartDay and kEndDay, currently set at 6 and 20 respectively. Thus the clock will display in night style between the hours of 8pm and 6am. The only settable property implemented by this clock widget is the timeZone, an integer which adjusts the time displayed relative to universal time (UTC).
