In My current project, I am using Sequalize ORM with Mysql.
This is the timestamp I am passing to be stored in the database  2022-03-14 12:50:57.519
But after storing the data, it automatically gets converted to UTC
 2022-03-14 07:20:57
timedatectl output
           Universal time: Mon 2022-03-14 07:55:56 UTC
