What local time will it be for teams in different countries? How does it convert to Wellington, NZ time zone? What time and day will it be in San Francisco? World Clock users often need to convert the time between time zones. In case for a stock exchange clock, you can have one colour for the morning trading session, another for the afternoon session, another for London's LSE VWAP and so on.
You can have up to 10 differently defined colours per clock to identify various time periods.
Notice that the number of available colours (we call them clock profiles) is not limited to two as in market open / closed situation. Here, you can see that NYSE is open for trading, while London's LSE and Tokyo's TSE are not. World Clock with three stock exchanges in taskbar
