问题
Setting a timestamp column to SYSDATE by default, stores it as UTC. Is it possible to change the timezone so SYSDATE stores dates and times to a different timezone?
So far, I've checked the SET command but I'm not sure if it is possible to use it to change the timezone.

Basically, the answer is no. According to the documentation:
TIMESTAMP values are UTC, not local time, in both user tables and Amazon Redshift system tables.
Note Timestamps with time zones are not supported.
If you need the queries to return data in different timezone, you can use the CONVERT_TIMEZONE function, with either constant timezone value (or query parameter), or joining the result to a configuration table which contains the required timezone.
