Was hunting around for how to do this, and couldn't find any examples, but
eventually figured it out.
Goal is to have all dates coming out of Postgres to be in UTC, regardless
of the DBA's timezone configuration.
Key piece of code is as follows:
import sqlalchemy
def set_utc_on_connect(dbapi_con, con_record):
c = dbapi_con.cursor()
c.execute("SET TIME ZONE UTC")
c.close()
sqlalchemy.event.listen(sqlalchemy.pool.Pool, 'connect', set_utc_on_connect)
Now all connections in the pool will have their timezone set to UTC, so all
queries will return UTC for datetime objects with timezone specified.
Just posting it here incase someone else needed the info.
Cheers,
~Owen
