How do I add timezones to my Datetime values?

SQL logs timestamps in two formats: timestamp and timestamptz. timestamp refers to timestamp without timezone, whereas timestamptz refers to timestamp with timezone. Benchling warehouse stores datetime data in UTC timezone.

Therefore, if you’d like to show timezones in your query, cast your timestamp value to timestamptz before converting to your desired timezone as shown below:

SELECT
timezone('US/Pacific', created_at.datetime::timestamptz) as "Created Time"
FROM org.registry_entity$rawAdditional resource
