datetimepicker bootstrap, set default date

Is it possible to set the default date to the current date? This is my current code:

 Selected Date: {{ data.dateDropDownLink | date:'yyyy-MM-dd HH:mm a' }}
            <div class="dropdown">
                <a  class="dropdown-toggle" id="dropdown1" role="button" data-toggle="dropdown" data-target="#" href="#">Click here to show calendar</a>
                <ul class="dropdown-menu" role="menu">
                    <datetimepicker data-ng-model="data.dateDropDownLink" data-datetimepicker-config="{ dropdownSelector: '#dropdown1' }"/>
                </ul>
            </div>

 angular.module('ui.bootstrap.datetimepicker', [])
    .constant('dateTimePickerConfig', {
      dropdownSelector: null,
      minuteStep: 2,
      minView: 'minute',
      startView: 'day'

    })
