1# Simple Clock
2
3### Introduction
4
5This sample exemplifies how to implement a simple clock application using the eTS UI capability.
6
7### Usage
8
9The UI uses **setInterval** to update the time at regular intervals and uses **Canvas** to draw the clock, where the rotation angles of the clock hands are obtained through calculation.
10
11For example, **2 * Math.PI / 60 * second** indicates the rotation angle of the second hand.
