控制器内方法：
//因法定节假日调休而上班的周末，这种情况也算工作日.因为这种情况少，可以通过手动配置$specialBusinessDay=['2023-04-23','2023-05-06','2023-06-25','2023-10-07','2023-10-08',];$calculator = new Dayscalculator(date('Y-m-d'), //当前时间Dayscalculator::getholidays(), // 获取节假日的时间[Dayscalculator::SATURDAY, Dayscalculator::SUNDAY],$specialBusinessDay);$calculator->addBusinessDays(2); // 2个工作日后的时间$afterBusinessDay = $calculator->getDate();// 开始时间$start_time = time();// 完结时间$should_time = strtotime($afterBusinessDay.date('H:i:s'));
