Hi Zahid,

the additional MySQL config for the timestamps should go into a config file for 
MySQL. By default, it is called my.cnf. But you can pass it as a cli option, 
when starting the mysql daemon (as cited in your message). As an option to the 
mysql daemon  mysqld, it defines the behavior of only the mysql daemon, so you 
cannot set it on client side. The airflow.cfg is the wrong place. It might 
work, but maybe in the long run not as expected due to quirks with MySQL not 
following the SQL standard very closely.
Best, Lars
