Canvas Clock Start
In these chapters we build an analog clock using HTML Canvas.
Part V - Start the Clock
To start the clock, call the drawClock function at intervals:
JavaScript:
var canvas = document.getElementById("canvas");
var ctx = canvas.getContext("2d");
var radius = canvas.height / 2;
ctx.translate(radius, radius);
radius = radius * 0.90
//drawClock();
setInterval(drawClock, 1000);

Example Explained
The only thing you have to do (to start the clock) is to call the drawClock function at intervals.
Substitute:
drawClock();
With:
setInterval(drawClock, 1000);
The interval is in milliseconds. drawClock will be called for each 1000 milliseconds.
