What is the meaning of using <code>days</code> * <code>24</code> * <code>60</code> * <code>60</code> * <code>1000</code> in a cookie? I've seen it quite a lot and I don't understand what it means. I need to create a function that reads the cookie and puts the value in a text box while uploading the page. <pre class="prettyprint"><code><body onload="readCookie()"> </code></pre>

Basically, 1000 is used here just for converting seconds to milliseconds. Number of seconds in a day = 24 * 60 * 60 = 86400 seconds. 1 second = 1000 milliseconds. So after calculating the expression, the result is in milliseconds. days * 24 * 60 * 60 * 1000 = days * 86400000 ms
