However not great with mysql and still don't see how I can still use the original select statement and work in a function like above, so that converts the timestamp column and shows as seconds ago instead. TIMESTAMP_TRUNC is very handy for aggregating your data by a particular date_part, like HOUR, while also accounting for different timestamps. ? I hope now I presented problem a way better. Timestamptz is a zone-aware data type of date and time, the default timezone of the PostgreSQL database is UTC which means when we insert any value in the timestamptz data type column, it will automatically convert into UTC.
