Sequelize:如何从现在开始添加12小时

const Sequelize = require('sequelize');
const Op = Sequelize.Op;

// 创建Sequelize实例
const sequelize = new Sequelize('database', 'username', 'password', {
  host: 'localhost',
  dialect: 'mysql'
});

// 定义模型
const Model = sequelize.define('Model', {
  // 模型属性
  createdAt: {
    type: Sequelize.DATE,
    defaultValue: Sequelize.NOW
  },
  updatedAt: {
    type: Sequelize.DATE,
    defaultValue: Sequelize.NOW
  }
});

// 添加12小时
const now = new Date();
const twelveHoursLater = new Date(now.getTime() + 12 * 60 * 60 * 1000);

// 更新模型
Model.update(
  { updatedAt: twelveHoursLater },
  { where: { updatedAt: { [Op.lte]: now } } }
)
  .then(() => {
    console.log('更新成功');
  })
  .catch((error) => {
    console.error('更新失败', error);
  });
