The sample code

Set the field to service-side time when new records are added:

const cloud = require('wx-server-sdk')
cloud.init()
const db = cloud.database()
exports.main = async (event, context) => {
  try {
    return await db.collection('todos').add({
      description: 'eat an apple',
      createTime: db.serverDate()
    })
  } catch(e) {
    console.error(e)
  }
}

The update field is one hour after the service side time:

const cloud = require('wx-server-sdk')
cloud.init()
const db = cloud.database()
exports.main = async (event, context) => {
  try {
    return await db.collection('todos').doc('my-todo-id').update({
      due: db.serverDate({
        offset: 60 * 60 * 1000
      })
    })
  } catch(e) {
    console.error(e)
  }
}
