Date and Time - Formatting a date or time in JavaScript

Examples of Use

Initialization

	<script src="m_date.js" type="text/Javascript" charset="utf-8" ></script>
	<script type="text/javascript">
		// we initialize an object that use current time ( time when object m_date was created )
		var date_format	= m_date();

		document.write("<pre>");

		document.write("\n	Date: HH:mm:ss » "+m_date().format("H:i:s"));

		document.write("\n	Date: YYYY:MM:dd » "+m_date().format("Y:m:d"));

		document.write("</pre>");
	</script>

Using always the current time or changing IT

	// initialization of object
	var date_format	= m_date();

	// renew current time in object
	m_date().setTime();
	// alert the current time
	alert(m_date.format("Y:m:d H:i:s"));

	// add a specific time **May 13 2012 13:45:20**
	m_date().setTime('2012 5 13 13:45:20');
	// alert updated time
	alert(m_date.format("Y:m:d H:i:s"));

	// a shorter mode to write
	alert(m_date.setTime('2012 5 13 13:45:20').format("Y:m:d H:i:s"));

Relative time Changing

	// initialization of object
	var date_format	= m_date();

	// renew current time in object
	m_date().setTime();
	// alert the current time
	alert(m_date.format("Y:m:d H:i:s"));

	// add + 60 seconds
	m_date().setTime(60*1000);
	alert(m_date.format("Y:m:d H:i:s"));

	// now reducing + 120 seconds
	m_date().setTime(-120*1000);
	alert(m_date.format("Y:m:d H:i:s"));

Escaping chars

	// initialization of object
	var date_format	= m_date();

	// renew current time in object
	m_date().setTime();
	// alert the current time but,
	//	add a char "T" at the beginning of response
	alert(m_date.format("\\T Y:m:d H:i:s"));

Changing Months Names

	// initialization of object
	var date_format	= m_date();
	// change months names
	date_format.months	= [
		'Ianuarie','Februarie','Martie','Aprilie','Mai','Iunie',
		'Iulie','August','Septembrie','Octombrie','Noiembrie','Decembrie'];
	// alert the current month in short and long form
	alert(m_date.format("M F"));

	// change days names
	date_format.days	= [
		'Duminică','Luni ','Marti','Miercuri','Joi','Vineri','Sambata'];
	// alert the current month in short and long form
	alert(m_date.format("l D"));
