I'd like to set a default time for the two datetimepickers below. The first (Start time) should be 00:00:01 unless otherwise specified (by the user). The second (End time) should be 23:59:59 unless otherwise specified (by the user).

datetimepicker seems to provide a default date option, but no default time option.

You can pass a Date object to defaultDate parameter.

var now = new Date();
var def1 = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 0, 0, 1);
var def2 = new Date(now.getFullYear(), now.getMonth(), now.getDate(), 23, 59, 59);

$(function() {
  $('.date:eq(0)').datetimepicker({
    defaultDate: def1,
    format: 'YYYY-MM-DD HH:mm:ss'
  });
  $('.date:eq(1)').datetimepicker({
    defaultDate: def2,
    format: 'YYYY-MM-DD HH:mm:ss'
  });
});
