WorldClock2

Displays a list of World Clocks in a single window. This list consists of few predefined timezones as well as additional timezones added by the user either by selecting from a drop down list of timezones or by manually adding a timezone name understood by the standard js Intl.DateTimeFormat. The time is taken from the local system time, so automatically works offline. Ideally chrome os should have come with such a app, but as its missing, I had to scratch my itch, along with experimenting on javascript and web environment. This is my 3rd experiment as part of learning by experimenting. Clearing or Adding of TimeZones may not update the GUI sometimes, in which case just restart the App and you will notice that it is suitably updated.
