Answer 2

Bootstrap datetimepicker uses moment library so make use of it like this,

var dateNow = new Date();
$('#current_date').datetimepicker({
    defaultDate:moment(dateNow).hours(0).minutes(0).seconds(0).milliseconds(0)
});

Simplified version of @Freddy's answer.

var dateNow = new Date();
$('#current_date').datetimepicker({
    defaultDate:moment(dateNow).startOf('hour')
});

startof can take various arguments. More details in MomentJS documentation.
