How to get Unix timestamp using Bootstrap-datetimepicker

I am using 3rd party date time picker from https://eonasdan.github.io/bootstrap-datetimepicker/

It is working fine, however, I'd like to get the value in Unix timestamp format. How do I do that? There is no formatting option for Unix. https://eonasdan.github.io/bootstrap-datetimepicker/Functions/#format

function getValue() {
    var date = $('#datetimepicker1').data('date');
    alert(date); // shows 05/25/2017 5:43 PM
}


<div class='input-group date' id='datetimepicker1'>
    <input type='text' class="form-control" />
    <span class="input-group-addon">
        <span class="glyphicon glyphicon-calendar"></span>
    </span>
</div>

The eonasdan datetimepicker has a good API that you can use to programmatically interact with the picker.

You can use the date() method that:

Returns the component's model current date, a moment object or null if not set.

Since the value return by date() is a moment object you can use unix() to get Unix timestamp (the number of seconds since the Unix Epoch).

Here a working sample:

function getValue() {
  var date = $('#datetimepicker1').data("DateTimePicker").date();
  if( date ){
    alert(date.unix());
  }
}

$('#datetimepicker1').datetimepicker();

<div class='input-group date' id='datetimepicker1'>
    <input type='text' class="form-control" />
    <span class="input-group-addon">
        <span class="glyphicon glyphicon-calendar"></span>
    </span>
</div>

<button onclick="getValue()" class="btn btn-primary">Get value</button>

Remember that, as the docs says:

Note All functions are accessed via the data attribute e.g. $('#datetimepicker').data("DateTimePicker").FUNCTION()
