It is a fine widget for your notification screen – World Clock - Local Time Review

I have used the widget only for a short time, but the widget is solid, looks good on the notification screen and has the added benefit of the sun rise, transit and set times for each location selected. If you find yourself needing a world time widget and you live on the notification screen, then this is a good, solid widget for that purpose. There are minor customizations allowed in the settings. The labels for each clock are editable and the order of the clocks can be set automatically by a switch so they are set from west to east or they may be arranged in a custom order by dragging. Each clock has a call time to set the beginning and end hours for calling. This allows you to see at a glance if the person you want to call would be available. There is also a switch to let you set all clocks for sunrise and sunset as the call hours limitation. My criticisms are minor. The clocks are only digital. Analog is not an option that is available. Another is that the app basically requires the in app purchase to really function to its full potential. Unless the only time zones you need are the ones that come set in the app, you need to unlock the database to set the time zones you want to display. Beyond these minor complaints. it is a good widget and I would recommend it.
