Sample time stamp plugin

$('p[time]').live('mouseover', function() {
	var insertion = $(this);
  var insertionTime = insertion.attr('time');
  
  var timeSpan = insertion.find('span.time');
  if (timeSpan.length) {
    timeSpan.show();
  } else {
    var date = new Date();
    date.setTime(insertionTime * 1000);
    // determine how you want to format your time stamp here
    $('<span/>')
    .addClass('time')
    .css({
      'float': 'right',
      'background-color': '#FFF',
      'padding': '1px 5px 1px 5px',
      'font-size': '0.8em',
      '-moz-border-radius': '3px',

      'border-radius': '3px'
    })
    .html(date.toString())
    .appendTo(insertion);
