关于 Timestamp ERROR 1292 (22007) 错误理解

现象

插入时间报错：

• mysql 中

ERROR 1292 (22007): Incorrect datetime value: '1970-01-01 00:01:00' for column 'agent_start_time' at row 1

• TIDB 中

ERROR 1292 (22007): invalid time format: '{1970 1 1 0 1 0 0}'

原因

TIMESTAMP 包含了日期和时间部分，值的范围是UTC时间 '1970-01-01 00:00:01' 到 '2038-01-19 03:14:07'

• 当插入时间 1970-01-01 00:01:00 报错的原因：
  1.sql_mode 包涵了STRICT_TRANS_TABLES：严格模式，非法数据值被拒绝
  2.系统时区非 UTC ，time_zone 为 system或者为 '+8:00'

解决方案

• 1.修改 sql_mode ,删除 STRICT_TRANS_TABLES 模式，但是会改变数据为默认
• 2.修改 linux 系统时区或者设置 time_zone 为'+0:00'，可以保留原数据

测试

• MySQL 中: 修改 sql_mode || time_zone
