添加验证方法：

/****************************添加自定义validate的开始结束时间验证方法*********************/
jQuery.validator.methods.compareDate = function(value, element, param) {
    //var startDate = jQuery(param).val() + ":00";补全yyyy-MM-dd HH:mm:ss格式  
    //value = value + ":00";  
    var startDate = jQuery(param).val();
    var date1 = new Date(Date.parse(startDate.replace("-", "/")));
    var date2 = new Date(Date.parse(value.replace("-", "/")));
    return date1 < date2;
};

使用：

$('#honor_form').validate({

        honor_id: {
            required: true,

            compareDate:"#honor_time_start",

        honor_descript: {
