About the HTC Clock widget
The HTC Clock widget that’s by default added on the Home screen
shows your current date, time, and location. You can tap the weather
image on this widget to open the Weather application and check for
more weather forecasts. See “Checking weather” for details.
The HTC Clock widget comes in a variety of looks and designs. You
can add another clock widget to the extended Home screen, if you
want to have another clock that shows the time of another city. To find
out how you can add a widget, see “Personalizing your Home screen
with widgets“ in the Personalizing chapter.
