mysqldump导出数据timestamp列时间会变化

/apps/svr/mysql57/bin/mysqldump -uroot -p -S /tmp/mysql3306.sock  -c -t --skip-extended-insert --set-gtid-purged=OFF school_archives  td_query_log --where=" id = 104348003 " > /apps/tmp/td_query_log_20210107.sql

导出时候要加 --skip-tz-utc 禁止mysqldump设置时区,才是实际时间( 或者 不要把文件分割,直接导入也不会有问题)

/apps/svr/mysql57/bin/mysqldump -uroot -p -S /tmp/mysql3306.sock  -c -t --skip-extended-insert --set-gtid-purged=OFF  --skip-tz-utc school_archives  td_query_log --where=" id = 104348003 "
