JavaScript 1.3 introduces new and modified Date methods to support a full-year notation, milliseconds, and Universal Coordinate Time. The following table summarizes the new methods:

Method	setFullYear()
Parameters	<year>(mandatory) <month>(optional) <day of the month>(optional)
Description	Sets the year of the specified date according to local time. If you don't specify the <month> and <day of the month>, the values returned from getMonth() and getDate() are used. Notice you cannot specify the <day of the month> without specifying the <month>. If you specify a parameter outside its expected range, other parameters will be updated accordingly. If, for example, you specify 15 for the <month>, the <year> will be incremented by one, and the <month> will be set to 3.
Example	var myBirthYear; myBirthDate = new Date(); myBirthDate.setFullYear(1998);
JavaScript 1.2	setYear()

Method	getMilliseconds()
Parameters	None
Description	Returns the milliseconds in the specified date according to local time. The return value is between 0 and 999.
Example	var myBirthDayMS; myBirthDate = new Date(); myBirthDayMS = myBirthDate.getMilliseconds();
JavaScript 1.2	None

Method	setMilliseconds()
Parameters	<milliseconds>
Description	Sets the milliseconds in the specified date according to local time. The parameter value should be between 0 and 999. If you specify a number outside this range, other date variables in the Date object will be incremented to accommodate your number. If you specify 1012, for example, the number of milliseconds in the Date object will be 12 and the number of seconds will be incremented by 1.
Example	myBirthDate = new Date(); myBirthDate.setMilliseconds(103);
JavaScript 1.2	None

Method	toUTCString()
Parameters	None
Description	Converts a date to a string, using UTC convention. This method behaves the same as toGMTString(), but you should use the toUTCString() instead. The latter is kept for backward compatibility purposes only.
Example	var myBirthMonth; myBirthDate = new Date(); myBirthMonth = myBirthDate.getUTCMonth();
JavaScript 1.2	getMonth()
