Answer 1

there are no configuration options to change the content of the tooltip
but a custom tooltip can be provided
see following working snippet
a tooltip column is inserted and populated with information from the data
google.charts.load('current', {
callback: function () {
var container = document.getElementById('chart_div');
var chart = new google.visualization.Timeline(container);
var dataTable = new google.visualization.DataTable();
dataTable.addColumn({type: 'string', id: 'RowLabel'});
dataTable.addColumn({type: 'string', id: 'BarLabel'});
dataTable.addColumn({type: 'date', id: 'Start'});
dataTable.addColumn({type: 'date', id: 'End'});
dataTable.addRows([
['165414 fine-turbo ers', 'Cpus 24 - 0.543h', new Date(2016,07,20, 13,37,32), new Date(2016,07,20, 15,43,19)],
['165418 fine-turbo ers', 'Cpus 24 - 0.534h', new Date(2016,07,20, 14,47,12), new Date(2016,07,20, 16,40,09)],
['165427 fine-turbo ers', 'Cpus 24 - 0.265h', new Date(2016,07,20, 18,01,23), new Date(2016,07,21, 00,02,53)],
]);
dataTable.insertColumn(2, {type: 'string', role: 'tooltip', p: {html: true}});
var dateFormat = new google.visualization.DateFormat({
pattern: 'M/d/yy hh:mm:ss'
});
for (var i = 0; i < dataTable.getNumberOfRows(); i++) {
var duration = (dataTable.getValue(i, 4).getTime() - dataTable.getValue(i, 3).getTime()) / 1000;
var hours = parseInt( duration / 3600 ) % 24;
var minutes = parseInt( duration / 60 ) % 60;
var seconds = duration % 60;
var tooltip = '<div class="ggl-tooltip"><span>' +
dataTable.getValue(i, 1) + '</span></div><div class="ggl-tooltip"><span>' +
dataTable.getValue(i, 0) + '</span>: ' +
dateFormat.formatValue(dataTable.getValue(i, 3)) + ' - ' +
dateFormat.formatValue(dataTable.getValue(i, 4)) + '</div>' +
'<div class="ggl-tooltip"><span>Duration: </span>' +
hours + 'h ' + minutes + 'm ' + seconds + 's ';
dataTable.setValue(i, 2, tooltip);
}
chart.draw(dataTable, {
tooltip: {
isHtml: true
}
});
},
packages: ['timeline']
});
.ggl-tooltip {
border: 1px solid #E0E0E0;
font-family: Arial, Helvetica;
font-size: 10pt;
padding: 12px 12px 12px 12px;
}
.ggl-tooltip div {
padding: 6px 6px 6px 6px;
}
.ggl-tooltip span {
font-weight: bold;
}

This question already helped me too much, but if someone want change the time format in timeline
hAxis: {
format: 'HH:mm'
},
