Changes

The Date object enables the JavaScript develper to create a Date object initialized to a specific time and date, or to create a date object that reflects the current ''system time'' on the computer on which the browser is running. There are two important things to note when working with the JavaScript Date object. Firstly, when reading the date and time of the user's computer you are completely at the mercy of the user's ability to set and maintain the correct day and time on their computer. Secondly, whilst you can read the system date and time set on the user's computer, and change those settings within your Date object instance, you ''cannot'' change the computer's system date and time. No matter what methods you call or properties you change on your Date object, the user's system date and time remain unaltered.
