将 UTC 设置为默认日期时区

Question

我已经成功安装并配置了TypeORM；我可以添加新记录、搜索等。我尝试将默认时区设置为UTC4 小时...但没有成功

我已将节点 TZ 配置设置为UTC，当我打印时，console.log(process.env.TZ)它会UTC按预期返回。

难道我做错了什么？我的“用户”实体代码：

import {Entity, PrimaryGeneratedColumn, Unique, Column, CreateDateColumn, UpdateDateColumn, BaseEntity} from "typeorm";

@Entity()
//@Unique(['email'])
export class User extends BaseEntity {
  @PrimaryGeneratedColumn("uuid")
  id!: number;

  @Column()
  email!: string;

  @Column()
  password!: string;

  @CreateDateColumn({name: 'created_at', type: 'timestamp'})
  createdAt!: Date;

  @UpdateDateColumn({name: 'updated_at',type: 'timestamp'})
  updatedAt!: Date;
}

和连接配置：

{
  name: 'default',
  type: 'mysql',
  host: 'localhost',
  port: 3306,
  username: 'root',
  password: 'supersecret',
  database: 'multichat',
  timezone: 'Z',
  syncronize: true,
  logging: false,
  entities: [
    '/var/www/html/projects/sluy/multichat/api_express/src/database/entities/**/*.ts'
  ],
  migrations: [
    '/var/www/html/projects/sluy/multichat/api_express/src/database/migrations/**/*.ts'
  ],
  subscribers: [
    '/var/www/html/projects/sluy/multichat/api_express/src/database/subscribers/**/*.ts'
  ],
  cli: {
    entitiesDir: '/var/www/html/projects/sluy/multichat/api_express/src/database/entities',
    migrationsDir: '/var/www/html/projects/sluy/multichat/api_express/src/database/migrations',
    subscribersDir: '/var/www/html/projects/sluy/multichat/api_express/src/database/subscribers'
  }
}

Answer 1

看来 TypeORM 的连接选项timezone无法与 mysql 正常工作： https: //github.com/typeorm/typeorm/issues/5895。

可能发生的情况是您的连接正在从系统获取时区信息。您可以使用 来验证这一点SELECT @@session.time_zone;。

解决方案

对我有用的是在启动服务器时手动设置时区信息：

await manager.query(`SET GLOBAL time_zone = '+00:00';`)
await manager.query(`SET time_zone = '+00:00';`)
