How to extract timezone from timestamp in postgresql?

@giovanny.lueilwitz 

You can extract the timezone from a timestamp in PostgreSQL using the timezone function.

Here is an example query that demonstrates how to extract the timezone from a timestamp column in a table:

1
2

SELECT timestamp_column AT TIME ZONE 'UTC' AS timezone
FROM your_table_name;

In this query, timestamp_column is the name of the column that contains the timestamp values, and your_table_name is the name of the table that contains the timestamp column.

The AT TIME ZONE 'UTC' part of the query specifies the timezone that you want to extract from the timestamp column.

You can replace 'UTC' with the specific timezone that you want to extract from the timestamp column.

For example, if you want to extract the timezone in Pacific Standard Time (PST), you can replace 'UTC' with 'PST'.
